Pre-filter

	Special filters P - M - A Three-stage filtration - pre-filter, micro-filter, activated carbon filter
	Suitable for all applications where the standard centrifugal separators do not afford the desired efficiency. The pre-filters and micro-filters are equipped with an automatic drain valve. All devices can be supplied with or without a differential pressure gauge. The differential pressure gauge indicates the degree of contamination of the filter element as a function of the pressure drop.
	Input pressure:		Min. 4 bar, max. 16 bar
	Medium and ambient temperature:		+5 °C to +60 °C
	Body and filter bowl:		Aluminium
	Indicating range of differential pressure gauge:		0 to 2 bar

	Pre-filter For filtering out solid impurities larger than 2 µm and for moisture separation. For connection upstream of a micro-filter or a combination micro-filter/activated carbon filter.
	Filter rating:		2 µm
	Particle separation:		2 µm
	Efficiency:		99.99%
	Filter insert:		Polyethylene (with 45% cavity)
	Flow rate measurement:		At P₁ = 6 bar and pressure drop Δ_p = 0.5%
	More information:		Data sheet 1-17 Operating Manual 17-15
