Orion Motor Tech 3.5 CFM HVAC Vacuum Pump
This Orion Motor Tech single stage vacuum pump comes with a 1/4 HP all-copper motor providing a 3.5 CFM flow rate. It efficiently evacuates air conditioners using refrigerants like R12, R22, R134a, R410a, and R502, drawing vacuum levels as low as 37.5 microns (5 Pa) for quick servicing. Constructed with a durable aluminum alloy casing, it ensures heat dissipation and corrosion resistance. The unit features an intake filter and oil mist trap that protect the pump’s internal parts. The oil reservoir has a sight glass and scale for easy monitoring, complemented by a nonslip handle for portability.
VIVOHOME Dual Stage 5 CFM HVAC Vacuum Pump Kit
The VIVOHOME 1/2 HP dual stage vacuum pump is designed with a sparkless motor and ignition-proof switch, making it safe for handling mildly flammable refrigerants such as R32 and R1234yf. It delivers a 5 CFM flow rate with an ultimate vacuum of 0.2 Pa within 3 minutes. The pump features multiple hose adapters for broad compatibility with common refrigerants including R22, R134a, and R410a. Safety and noise reduction are prioritized with motor current protection, a stainless steel filter, and an oil mist cap plus exhaust filter helping to maintain a quieter operation under 65 dB.
XtremepowerUS 4 CFM Air Vacuum Pump HVAC Kit
This 1/3 HP XtremepowerUS vacuum pump provides a 4 CFM air flow, making it efficient for air conditioner and refrigeration maintenance. The pump’s die-cast aluminum casing ensures durability and lighter weight. It also houses a high-volume internal cooling fan to support prolonged use without overheating. Oil management is simplified with a dedicated fill port and a bottom drain plug, supported by an oil level spill meter to maintain proper lubrication. Brass-fitted safety caps help prevent oil leakage during transportation and storage.
VEVOR 9 CFM 2 Stage Rotary Vane Vacuum Pump
The VEVOR 2-stage rotary vane vacuum pump boasts a powerful pure copper motor delivering a 9 CFM flow rate and achieving an ultimate vacuum down to 0.2 Pa. Built for robust HVAC and automotive AC work, it offers fast evacuation ensuring thorough system dehumidification. The pump integrates a cooling fan and heat dissipation design to maintain stable, long-lasting performance even during lengthy operations. Equipped with both 1/4″ SAE and 1/2″ ACME ports, it supports a wide range of refrigerants including R134a, R22, and R410a, suitable for various units from automotive AC to smaller tonnage HVAC systems.
VIVOHOME VG Series 5 CFM 2 Stage Vacuum Pump & Gauge Kit
This VIVOHOME VG Series dual-stage vacuum pump features a 1/2 HP pure copper motor sustaining 5 CFM flow with a deep ultimate vacuum of 15 microns (0.2 Pa). It excels in HVAC and refrigeration servicing with reliable air removal and moisture evacuation. The pump prioritizes quiet and cool operation through a powerful internal fan, T-shaped fins, and mesh ventilation. Filtration systems are implemented to block dust and separate oil mist from exhaust, extending the pump’s lifespan. The included 3-way manifold gauge offers precise pressure readings and is paired with durable, color-coded hoses rated for high pressure, ensuring a secure, leak-proof setup.
Buying Guide: Choosing the Right Air Conditioner Vacuum Pump Kit
Performance (CFM and Vacuum Depth): Select a pump with adequate flow rate (CFM) suitable for your system size. Higher CFM pumps like 9 or 5 CFM enable faster evacuation, important for large HVAC or automotive systems. Depth of vacuum (microns or Pa) indicates the pump’s ability to remove moisture and air; lower values mean better evacuation.
Single Stage vs Dual Stage: Dual-stage vacuum pumps provide deeper vacuum and better moisture elimination, ideal for professional use and complex systems. Single stage pumps are often sufficient for light to medium duty applications.
Motor Power and Safety Features: Motors rated 1/4 HP to 1 HP balance power and efficiency. Look for sparkless motors and ignition-proof switches if working with mildly flammable refrigerants to enhance operational safety.
Compatibility and Accessories: Ensure the pump kit supports refrigerants used in your systems (R134a, R410a, R22, etc.). Kits including manifolds, hoses, leak detectors, and multiple connectors increase versatility and ease HVAC maintenance.
Durability and Cooling: Aluminum alloy casings resist corrosion and dissipate heat. Integrated cooling fans and motor heat fins prolong pump life during extended use.
Noise Levels: Quieter pumps with noise reduction features improve the working environment, especially in indoor or residential settings.
Oil Management: Pumps with easy oil fill/drain ports, sight glasses for oil level monitoring, and anti-backflow designs streamline maintenance and ensure pump longevity.
