Gast DOA-P504-BN 1/8 hp 220/240V Diaphragm Vacuum Pump/Compressor

The Gast DOA-P504-BN is a new, oil-less dual-head diaphragm pump capable of operating as both a vacuum pump and a compressor, rated at 1/8 hp with a maximum vacuum of 25.5 in Hg and 0.9 CFM free air displacement. The motor operates on 230V AC / 50 Hz (confirmed from the nameplate visible in photos: DOA-P504-BN, 230V, 2.2A, 50 Hz), making this unit configured for international/European markets rather than standard North American 60 Hz service — buyers should confirm compatibility before purchase. The unit features dual gauges (one vacuum, one pressure), dual needle valves for independent flow adjustment, a built-in ON/OFF rocker switch, rubber anti-vibration feet, and a carry handle, housed in a die-cast aluminum body. It is oil-free by design, requiring no lubrication and producing no oil mist, which makes it suitable for laboratory, medical, environmental sampling, filtration, and light industrial applications where clean air is required. As a Gast DOA-series pump, it is compatible with standard Gast DOA-series service kits and diaphragm repair kits.
