Gap too large causes excessive leakage

1* due to unacceptable gaps around the slider opening to close the plate. I had .032" UHMW tape with glue. I applied one layer to the casting and another to the plate. After reducing the original slack by 1/16" there is still some slack left.

Pros
  • CONSTRUCTION: Blastgate features strong aluminum construction with high quality steel sliders designed for air leakage prevention, design flexibility and long life
Cons
  • Some difficulties

Just the right size and just what I needed

Perfect for my dust collection system. It's a little loose but when the DC is on it creates a good seal. When opened there will be a small amount of air leaking out but this is typical for all blast doors with a clean path I can make a styrofoam adapter to see if I can help close the gap once it is open.

Pros
  • INCLUDES: 5" Aluminum Push Plug
Cons
  • Not bad

A very high quality piece. Pro tip: if you have a .

Very high quality part. Pro Tip: If you're using 4-inch PVC sewer pipe to collect dust, use this dampener if you plan to run the pipe on both sides. The outside diameter of the 4" fitting is very close to the inside diameter of this valve. Simply cut the seam in half and attach one half to each side of the gate with silicone. The result is a smooth constant diameter seam. Use Powertec 4" Gates when transitioning from PVC to Flex.

Pros
  • FEATURES: Self-cleaning and clog-free groove design eliminating the need for constant cleaning and easy sliding breech and locking stop to ensure perfect breech alignment
Cons
  • Not all will fit

Steel blade that slides closed is too thin/soft

I applaud Powertec for giving us a cheaper alternative to a great blast gate design. However, they have cheapened the quality of the steel blade that slides in and out to the point where it's not worth the discounted price. The blade was warped on arrival so I took the blast hatch apart and flattened the blade as much as possible to ensure it would close securely when closed. Unfortunately, in a workshop there is a very high probability that one day the blade will bend and the seal quality will
