Fred,

I have vented my blower outside (cyclone) and it works great. I don't understand how reducing the back pressure could overload the motor. I would think it would actually reduce the load. Please educate me! I talked to Jet before doing it and they said there would not be a problem.

Mark,

The only realisitic way I know of is to remove the motor/blower from the bag assembly, turn the unit on its side and add either a cyclone or some other separator. Then just attach a duct through to the outside.

But I totally agree with Fred, on a unit this small I think you're wasting your time.

What are you using it for?

Keep in mind with venting outside you need replacement air which in Montreal is a critical consideration, depending on the size/cost of heating your shop.

My advice is to simply upgrade the filter to a canister, attach a small cyclone and use it as a mobile machine-to-machine collector.

Rick M -

How big were their shops and how much was the DC running?

Depending on the size of the shop, how much the DC is running, and how cold it is outside, and how you heat the shop, it can be a problem.

You couldn t be more wrong, but I ll leave it at that. You are correct that running it with no load is just fine, now adding air to the impeller adds load, hence more amps as the motor tries to overcome that load (and stay at it s stated RPM). Reducing backpressure at the discharge allows it to add air (and load). But with that, I m done…..

I believe you but intuitively it doesn't sound right. How can reducing the back pressure allow more air into the system? I would think the only load factor is on the inlet side.

I have no way of comparing filter vs. no filter on my unit, but I am going to put an ammeter on it just for my own info. It's never tripped a breaker but I'm curious now. All I know is by venting outside the performance increaded dramatically.
