Value ATEX 2-stage vacuum pump R290/R600

Value Maxivac ATEX 2-Stage Vacuum Pump

The Value Maxivac ATEX 2-stage vacuum pump is a two-stage vacuum pump designed for evacuating HVAC/R systems operating with flammable refrigerants such as R290 and R600a. The pump is ATEX-certified (CSA22ATEX1160X) for use in Zone 2 environments and complies with EN IEC 60079 standards, making it suitable for installations using A1, A2L, A2, and A3 refrigerants, both for new installations and maintenance.

Advantages and Features

• Spark-free, ATEX-certified design (CSANe 22ATEX1160X): safely operable with flammable refrigerants in explosive atmospheres (Zone 2, gas group IIA).
• Two-stage cylinder construction: achieves a final vacuum of 15 microns (total pressure) and 2 Pa (partial pressure), ensuring thorough evacuation of the system.
• Forced oil lubrication: guarantees stable sealing of the vanes, enhanced cooling, and extended pump lifespan.
• Built-in check valve: prevents oil backflow when the pump is switched off.
• Large oil level window: immediate visibility of oil level to detect shortages in time and prevent damage.
• Lifting hook: safe and convenient transportation in hard-to-reach locations such as rooftops.

Powerful Vacuum at Every Operating Frequency

At 50 Hz, the VA3-P7-EX delivers a flow rate of 6 CFM (170 L/min), and at 60 Hz, 7 CFM (198 L/min). The final vacuum of 15 microns guarantees complete removal of moisture and non-condensable gases from the refrigeration circuit, an absolute necessity when working with modern environmentally friendly refrigerants. The 3/4 HP motor at 230 V/50-60 Hz is robust enough for intensive daily use.

Installation, Maintenance, and Applications

The pump is mounted horizontally and connects via standard 1/4" and 3/8" SAE Flare fittings, compatible with common hose sets. Before use, the oil level is checked and topped up to the recommended oil capacity of 426 ml. The VA3-P7-EX weighs 12.6 kg and measures 346x130x287 mm. The pump is intended exclusively for professional HVAC/R technicians working with A2L and A3 refrigerants in the refrigeration and climate control industry.

The Value VA3-P7-EX combines ATEX-certified safety for flammable refrigerants with the deep vacuum performance of a two-stage pump, making it a reliable choice for technicians maintaining or installing future-proof refrigeration systems.
