Factors When Installing an Exhaust Removal System

Figure it out. The displacement of the engine x rpm will tell you how much air the engine puts out. For your purposes, consider the engine a positive displacement pump.

I'd go to Graingers (Disclaimer) and buy some exhaust fans and duct hose.

Or, get fancy and buy a 3HP centrifugal blower.

Except that the "air" is expanded as it passes through the cylinder. The clean air in takes up less volume than the dirty air coming out!

I have always had the opinion that the exhaust volume was 2.5 to 3 time the inlet volume of an IC engine due to temperature rise and combustion by-products. Depending on the operating RPM you might have more "air" than the fan could handle.

Safest is to deal with Nederman or Plymovent as the other poster suggested. If you like to experiment, have at it, but be careful of what you're breathing.

Try looking around at some of the products and design specs on this site:

or give their sales rep a call - they can give you some guidance.

If you have compressed air available, air amplifiers are the simplest solution.

Thanks.

The system is in fact manufactured by Nederman. With the total losses calculated to be 1625 Pa, I have chosen a fan with capacity 1750 m3/h. This is the highest capacity available for the model of fan I am restricted to using. It seems a little low to me with the given loss. Will a higher rpm/frequency make up for this?
