Product Description

The GAST DOA-P704-AA is a lab-model diaphragm pump rated at 1/8 HP and 115 volts, designed for compressed air and vacuum applications in laboratory and light industrial environments. It delivers up to 1.1 CFM of flow with a maximum working pressure of 60 psi (4.14 bar), making it suitable for tasks that require clean, oil-free air delivery. The pump accepts 50 Hz and 60 Hz power input, allowing use in both domestic and international facilities. Port connections are 3/8 inch NPT. Licensed HVAC technicians, lab equipment technicians, and industrial maintenance professionals typically install and service this unit.

This diaphragm pump is intended for laboratory and light industrial settings where a compact, self-contained compressed air source is required. Its oil-free diaphragm design eliminates contamination risk in sensitive applications such as sample handling, filtration, aeration, and analytical instrumentation. The unit measures 5.12 inches wide by 7.62 inches long by 7.59 inches high, fitting into confined bench-top or cabinet installations. The 3/8 inch NPT port accommodates standard laboratory and industrial tubing fittings.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air systems and applicable local codes. Disconnect and lock out all power before servicing or making any plumbing connections. Ensure the supply voltage matches the pump nameplate rating of 115 volts before energizing. All pneumatic connections should be pressure-tested after installation to verify leak-free performance before returning the system to service.
