	~~===Fans===~~
	This range of fans from 0.7Kw up to 18.5Kw is designed to give high energy efficiency for the volume being handled, whilst still delivering sufficient external system pressure to cover most of the range of commonly encountered problems. The fan impellors are of a backward inclined, plate type and are mounted direct onto the motor shaft. These are mounted on top of the unit giving easy access for wiring and servicing, and in the event of fire ensures that the motor is outside the air-stream.

Turn the normal filter cut-off down, and turn the filter envelope cut-off higher, and then program the filter envelope like a normal envelope.

	Takes a while to figure out, but its worth it – for example, turn the sustain on the filter envelope off, forget about the release and attack (set them to zero), and make the decay short – then turn up the release and wow! The thing to remember here is that its not the volume (amplitude) that your changing, it’s the cut-off frequency with the envelope, so you can create great effects with clever programming – such as emulating brass sounds by increasing the attack on the filter envelope.

			===Filter media===
			The filtration of the air is achieved by passing it through cloth arranged in a multi-pocket, envelope form. Standard units are supplied with [[bags]] manufactured in cotton fabric, however, other media are available for greater efficiency. These include plain needle felt fabrics, felts with either surface treatments or membranes, or alternatively felts manufactured incorporating epitropic fibres to give antistatic properties.
