The Automatic Draught Blocker for Ceiling Exhaust fans prevent draughts from entering your home through ceiling exhaust fans that are commonly found in kitchens, bathrooms, toilets and laundry rooms.

Saves up to 30% on Heating / Cooling: Stops your warmed winter air leaving via your exhaust fan. Stops the hot summer heat invading your home.

Easy Installation: The installation is simple and straightforward. We have provided step-by-step video instructions to guide you through it.

Low cost: the unit's cost is quickly offset by the energy savings it provides, so it pays for itself very fast (easily less than 1 year!).

Durable: Though the unit is lightweight, it is made from sturdy plastic that will last for years.


This is the original and best Draftstoppa created by a practical and creative Aussie gentleman with a big vision for energy savings.  The DraftStoppa was so innovative that is won the HIA Product of the Year in 2003. 

DraftStoppas are, and have always been, manufactured in Australia - in Victoria! 

A Draftstoppa is a device that prevents draughts from entering through kitchen, bathroom, laundry or toilet exhaust fans that are fitted in the ceiling.  It has recyclable plastic butterfly wings that open automatically when the exhaust fan is switched on, and close down when the fan is switched off. 

A DraftStoppa can also be fitted to 3-in-1 bathroom heat lamp units, but an electrician is required to rewire the switch to ensure that the fan is always on when the heating lamps are on.   [Learn more]

Will make your bathroom, ensuite much more comfortable. 
Works to manage draughts without compromising ventilation.
Does not interfere with the operation of the exhaust fan.
Prevents air from entering or escaping through the exhaust fan when not in use.
Highly durable.
Australian designed and developed.
Australian made and owned.

Test Results: 

Winter test results demonstrated, with an external temperature of 1ºC and an average internal room (10m x 4m x 2.7m - volume 108m³) and an inside ambient  temperature of 15.5ºC, the cold air inflow from the roof cavity through an unsealed fan into the room was measured at 13 litres / second.

This means that for every hour 46.8m³ of cold air would have entered the room.  The total volume of warm air would be replaced every 2 hours and 20 minutes.  Can you imagine what that is costing you!!!

      This is the original Draft Stoppa: pioneered and manufactured in Australia.   

      The DraftStoppa has a diameter of 350mm.
      The closed height of a draftStoppa is 160mm.
      When fully opened, the height of the DraftStoppa is 200mm.

      The DraftStoppa comes in 4 sections - two round sections and two butterfly wings.

      DraftStoppas have small rubber bumpers on each of the butterfly wings so their operation is silent when the wings close on the unit. 

      The round sections clip together, then the wings are clipped in at the top. 

      Don't be fooled by a sub-standard version.  Make sure you buy the original, Australian designed and made DraftStoppa. 

      Draft Stoppa is made from recyclable, fire retardant materials. 
      The Draught Stopper requires no maintenance and has no running costs.


        Easy but you need to be able to get into, and be comfortable moving around in your attic space

        How To

        Tools You You Will Need For Installation:

        • Ladder
        • Flashlight/headlamp
        • Clothes you don't mind getting dirty


        Q: What does this product do and how does it work?
        A: DraftStoppas are installed above exhaust fans to stop excessive air leakage when exhaust fans are not in use. This product has gravity operated butterfly wings that open when the fan is in use but close when the fan is switched off, preventing unwanted air leakage.

        Q: How is a DraftStoppa installed?
        A: The DraftStoppa comes with easy to follow instructions. Simply assemble the four components and drop it over the top of the exhaust fan. There is a notch for the fan electrical cable to pass through.

        Q: Are there any things to watch out for?
        A: Occasionally there are obstructions that cause fitting difficulty. The most common ones are:

        - The ceiling joists are too close together to accommodate the DraftStoppa as it is slightly wider than the exhaust fan.
        - There is a pipe above the exhaust fan.
        - The power outlet supplying the fan has been fitted too close to the fan.

        Q: Can I fit the DraftStoppa on my 3-in-1 heat lamp unit?
        A: Well yes and no. Technically it is possible with the use of a specific Adapter Plate AND rewire the electrical switch so that the fan is on any time the heat lamps are used. This is necessary to prevent melting the DraftStoppa. It is our view that a better approach is to replace the heat lamp unit with one that has a built-in back draught baffle.  However, we do offer the Adapter Plate if you wish to retain your existing fan.  [Learn more]

        Q: What if my exhaust fan is on the ground floor of a two story home?
        A: Usually the DraftStoppa can still be fitted, however the process is a little different. To fit the DraftStoppa into the inter-floor space (which is almost always a very draughty space) follow these steps:

        • Remove the fan grill as well as the fan from the ceiling. Let it hang by the electrical cord.
        • Take the DraftStoppa and fit the wings to each half of the round casing.
        • Put each half into the inter-floor space and then assemble the two halves within the inter-floor space.
        • Carefully replace the exhaust fan being careful to feed the electrical cable through the notch provided in the DraftStoppa.
        • Refix the fan into the ceiling and replace the grill.

        Q: Will I still be able to use my fan?
        A: This product should not prevent your fan from its natural function. If it does, then it may have inadvertently pushed into the side of the fan blades. Repositioning the DraftStoppa should clear the problem.

        Q: How do I get a good seal around the base of the DraftStoppa with the power cord in the way?
        A: There is a designated hole at the base of the fan that allows the power cord to fit.

        Q: Are there any tips for fitting the DraftStoppa?
        A: A couple of tips to help you successfully fit the DraftStoppa and achieve significant energy savings.

        • You need to be mindful that there is enough clearance AROUND the fan in the roof space.
        • You will need some clearance ABOVE the DraftStoppa for the flaps to open and close.
        • The joists in the ceiling need to be spaced wide enough for the Draft Stoppa to fit over the fan and still sit flat on your plasterboard. 

        Q: Is there anything special I need to know about the Draft Stoppa before it is installed?
        A: Yes - DO NOT leave it sitting in the sun (even for a short time) as UV rays will warp the butterfly wings on the DraftStoppa.  This will prevent the DraftStoppa from creating a seal between the flaps and the base.


        Q: Can I collect my order?
        A: Yes you can!  A “Ready for Pickup” email will be sent to you when you order is ready to be collected.  Please click this link for the Click and Collect details.  Note:  this Collection Centre is in Preston in Victoria, NOT Prestons in NSW.

        Q:  When will my order be delivered?

        Q: What happens if my order gets lost during transit?
        A: On rare occasions we have had orders go missing. ecoMaster has solid procedures in place and photograph every order that leaves our warehouse.  The delivery of our orders at our local post office are videoed and we track the progress of orders.  If a delivery date appears to be beyond expectation, we will raise a query with the freighter on your behalf.  If your order cannot be found during transit, we will send a replacement.  

        Q: What happens if my order is stolen after delivery?
        A: We will check with the freighter to ensure that the order was delivered to the correct address.  If that is confirmed, and your order has been stolen from your home after delivery, please raise a Police Report.  In practice, we have had very little of this behaviour.


        Q: What is the product warranty for DraftStoppa?
        A: DraftStoppa carries a product warranty of 5 years, as long as the product has been installed according to instructions.  

        Q: What is the installation warranty for DraftStoppa?
        A: As the DraftStoppa is a DIY product there is no warranty on installation.  

        We have known 'failures' of the DraftStoppa unit when:  

        • It was left sitting in the sun prior to installation. Whilst the DraftStoppa is heat resistant, is does not like UV which will cause the butterfly wings to warp. 
        • It was installed over a 3 in 1 heat / lamp / fan unit and the switch was not rewired according to the manufacturers instructions. 
        • The lugs that the butterfly wings are attached to have been snapped off due to excess pressure / impatient installation. 

        To get the best value for your investment, please, PLEASE watch the installation videos before you proceed.  

        If you have any questions, contact the ecoMaster team.  We are all ex-installers and have done this work thousands of times before.  We are here to help you.

        Q: What do I do if I have a problem with this product?  
        A: Refer to our Returns / Refunds page [Learn More].  Our Research and Development team will be keenly interested to learn of any product failure and will want images and samples of the product (if possible) so they can determine what the cause of failure was.

        Q: What happens if my order is damaged in transit?
        A: Our freighters have very strict policies on the ability to claim on insurance if your order arrives damaged.  There is a 48 hour window of receipt of goods for ecoMaster being able to advise the freighters of a damage claim.  PLEASE ensure you have advised us IMMEDIATELY if an order has been damaged on arrival.  Open your order immediately and check.  Outside of the 48 hour window, we are unable to make an insurance claim.

        DraftStoppa in East Bentleigh

        I can see improvement with thermal images before and after so thats good.
        I had clearance issues in my roof but overcame that with some timber and screws so that was all good

        HI Imre,

        It's fabulous to hear that you have seen improvements with our DraftStoppa. We understand that installation can sometimes have its challenges, but we're glad you were able to overcome them with some creative thinking. Thank you for your feedback!

        Easy Install

        Robust quality, easy to install from above or below ceiling. Effective draft reduction

        Hi Colin,

        Many thanks for the 5 star review. We really appreciate you being a customer and helping to share the word about us and our products.

        Great way to reduce drafts from fans

        These Draftstoppas are easy to assemble and simply sit over your bathroom exhaust fan. I have used them for many years and they noticeably reduce the cold air blowing into your bathroom, particularly on a cold Victorian day. I ordered mine on a Sunday and they arrived two days later. Fantastic service, highly recommended!

        Thank you for your kind review Arthur!
        We are so happy that our DraftStoppa has helped reduce drafts from your bathroom exhaust fan. It's great to know that you have been using this product for many years. Thank you for your continued support!


        I purchased this product from a hardware store about 10 years ago, and it is great. What isn't great is the stores now don't stock it, so I ordered it direct from the company. A companythat promotes itself to be all about saving the environment, but packed the small cover in a box twice it's size, adding insulation that I didn't order, burning up the carbon miles with wasted packaging, and charging almost the same price as the product to post the oversized parcel. I'm glad I don't need another one, as I wouldn't be fooled twice to order one again.

        Hello Brett

        Thanks for sharing your feedback.
        The DraftStoppa is an excellent device for sealing the draughts from your bathroom/ensuite/toilet areas. This is reflected in the numerous positive customer reviews about the product displayed on our website.
        Unfortunately, Draft Stoppas can be very easily damaged during the freighting process. A damaged/ non functioning DraftStoppa saves zero energy. So yes, it is a balance between a well padded unit versus a lightly packed but broken one.
        We have found that the safest way to avoid damage is to pack the DraftStoppa into a cardboard box and surround it with insulation as padding. This avoids damage during shipping especially when it is travelling interstate.
        The insulation can be popped into your roof space if you wish and we will add that the insulation itself is made from 80% recycled PET bottles. The cardboard boxes (also made from recycled materials) can simply be broken down and added to your fortnightly recycling bin.
        All freight charge rates are transparent on the store prior to completing your order.

        If you have any further feedback, especially about how the draftstoppa is performing we encourage you to give us a call on 1300 326 627. We welcome the opportunity to speak with you directly.

        I should have done this sooner!

        I’m really pleased after installing two DraftStoppa fan covers recently. Super easy to assemble and place over the fans, and definitely a quick win for draught proofing an old house. I only wish I’d done this years ago. A side benefit was the motivation to give the fans a long overdue clean!

        Hi Peter,

        Oh the overdue fan clean - don't we all dread that one! lol.
        Thanks for sharing your review with us and the community. Appreciate it!
        Have a fantastic day!
