Equipped with an ignition-proof on/off switch and a sparkless motor, the VIVOHOME vacuum pump is engineered for safe operation with A2L, such as R32 R1234yf and R454B, and other mildly flammable refrigerants, Powered by a 1/4 HP (180-Watt) motor running at 1728 r/min, it delivers a flow rate of 3.5 CFM and achieves an ultimate vacuum of 2 Pa in just 3-minutes, making it a reliable and secure choice for precise AC system maintenance. It is ideal for for maintaining R32, R1234yf, R454B, R410a, R134a, R12, R22, and R502 air conditioning systems. This manifold gauge ensures precise pressure measurement for refrigeration systems, It blends the best of dry and liquid-filled designs, featuring an oil-filled core to resist wear and a dry dial for better winter performance.
- Features dual 1/2 in. Acme and 1/4 in. sae ports, plus 4-adapters (2 x 1/4 in. male to 5/16 in. female for r410a, 1 x 1/4 in. male to 1/2 in. female, and 1 x 1/4 in. male to 1/2 in. female left-hand), making it compatible with r32, r1234yf, r454b, r410a, r134a, r12, r22, and r502 air conditioning systems
- 304-stainless steel coarse filter blocks contaminants from entering the pump chamber
- Motor current protection prevents overload and phase loss, avoiding overheating or damage
- Oil mist cap and cotton exhaust filter effectively capture oil mist, and the latter also helps reduce noise
- Integrated aluminum housing reduces leaks, while the visible oil window and bottom drain valve simplify maintenance
- Built with a shock-resistant core to protect internal mechanisms, this gauge includes a calibration screw for zero-setting and scales for r32, r410a, r1234yf and r134a refrigerants
- Weighs just 18.6 lbs. with an ergonomic handle and non-slip feet for easy transport
- Large sight glass allows clear refrigerant flow visibility, while color-coded gauges ensure accurate readings for refrigerant charging, diagnostics, and coolant recovery
- Easily identify the high-pressure (red), low-pressure (blue) and refrigerant adding (yellow) hoses
