BP20V/25V      Hamworthy V34H-AL

Compressors are air-cooled balanced vee design with powerful multi-blade cooling fans.  Fitted with inter-stage coolers incorporating drainable moisture traps, integrated aftercooler and pressure relief valve at each stage of compression.  Lubrication is by controlled splash and the crankcase is totally enclosed, so no oil vapour is vented to the atmosphere.  On the BP20V and BP25V a diagnostic pressure gauge is connected to each compression stage.

Purification

8V, 10V, 13V:  Hamworthy PAS 9 single-chamber system fitted with disposable cartridges filled with a combination of molecular sieve and activated carbon.  Filter base is fitted with safety valve, pressure-maintaining valve and moisture drain valve.  Cartridge process capacity under average temperature/humidity conditions is approx 28,800 cu ft (816 m³).  Air purity generally exceeds all recognised international standards.  A colour indicator shows when media is saturated or cartridge needs replacement (this can be done in a few minutes without special tools or any disturbance to high-pressure fittings).

20V, 25V: As above but Hamworthy PAS 5+9+9 3-chamber system.  The final chamber also includes a catalyst to convert carbon monoxide to carbon dioxide.  Filter process capacity under average temperature/humidity conditions is approx 56,000 cu ft (1586 m³). 

Charging facilities

These compressors are normally fitted with two filling hoses (8V, 10V, 13V) or three hoses (20V, 25V) for direct bottle filling.  Each hose incorporates a control valve, pressure bleed and connector to customer’s specification.
