HLVAP-OL-02-100 to HLVAP-OL-02-140 = Single Pump HLVAP-OL-02-150 to HLVAP-OL-02-170 = Duplex Pump (Duplex = 2 x pumps supplied on frame) Multi-bank dryer installations require multiples vacuum pumps. For example, 3 x CDAS LE 170 requires 3 x HLVAP-OL-02-170 pumps or alternatively consider connection to a centralised vacuum system. Stated flows are for operation at 7 bar (g) (102 psi g) with reference to 20°C, 1 bar (a), 0% relative water vapour pressure. For flows at other pressures, apply the correction factors shown below.

To select a dryer, first calculate the Minimum Drying Capacity (MDC) using the formula below then select a dryer from the flow rate table above with a flow rate equal to or above the MDC. Minimum Drying Capacity (MDC) = Max System Flow x CFMIT x CFMAT x CFMIP x CFOD Dryer Performance Dryer Models Dewpoint (Standard) ISO 8573-1:2010 Classification (Standard) Dewpoint (Option 1) ISO 8573-1:2010 Classification (Option 1) Dewpoint (Option 2) ISO 8573-1:2010 Classification (Option 2) °C °F °C °F °C °F CDAS LE 100 - CDAS LE 170 -40 -40 Class 2:2:2 -70 -100 Class 2:1:2 -20 -4 Class 2:3:2 ISO 8573-1 Classifications when used with Parker OIL-X pre/post filtration.
