Diaphragm compressor DAA-P501-EB

airACportable

Presentation The DAA-P501-EB diaphragm compressor is an oil-free 1/4 HP unit designed for reliable, low-noise operation in noise-sensitive industrial and laboratory environments. Rated for 115 VAC with a maximum continuous pressure of 60 PSI and an open-flow of 2.4 CFM (60 Hz), it delivers clean, contaminant-free air and precise pressure control.

General description The DOA and DAA series are compact, lightweight diaphragm compressors that can operate as compressors or vacuum pumps. They tolerate liquid ingress, work at low temperatures, and feature corrosion-resistant construction and air-tight design for contamination-free output. Standard units include a vacuum silencer and motor capacitor. A laboratory configuration is available with accessories (gauges, regulators, fittings, handle, rubber feet) and membrane/valve options (PTFE, neoprene, stainless steel).

Applications DOA and DAA series are suitable for medical, food & beverage, environmental monitoring, and industrial process control applications requiring precise fluid handling, sampling and measurement, and reliable continuous operation.

Key features

• Chemically resistant materials: high-performance thermoplastic polymer (PPS) and synthetic rubber (EPDM) for wetted components, resistant to chemicals, heat and corrosion.
• EMI suppression: protects sensitive electronic components.
• Versatile operation: functions as compressor and vacuum pump; available in dual-frequency, shaded-pole and permanent split capacitor (PSC) motor types; multivoltage options for global use.
• Reliability: durable materials and components reduce downtime and maintenance.
