ALLY 120 W Rechargeable Cordless Mini Air Pump and Compressor (for Boiler Expansion Vessels)

One of the biggest time losses for heating and cooling (HVAC) technicians in the field is carrying heavy compressors or tiring manual hand pumps to pressurise boiler expansion vessels during periodic maintenance. The ALLY 120 W cordless mini air pump, with its compact rechargeable design, frees technicians from this chore and makes service work faster and more professional.

A Practical Cordless Solution for Boiler Expansion Vessels

The integrated LED light on the unit is a great help, especially when working in narrow, dark boiler cupboards. Thanks to the presettable digital pressure display, you simply enter the pressure the expansion vessel needs (for example 1.0 or 1.5 bar) on the screen and pull the trigger. When the target pressure is reached, the fully automatic stop (Auto-Stop) function kicks in, preventing damage to the vessel diaphragm and giving an error-free charge.

Practical Note for Field Technicians

Technician's note: No more sweating with a manual hand pump when topping up the expansion vessel during periodic boiler maintenance! Fit the unit to the vessel's valve, set 1 bar on the digital display and start it. While the unit pumps the air you can deal with cleaning the boiler's filter or burner. The 3 different nozzles in the set also give wide flexibility, from your service van's tyres to your customer's bicycle.
