Rogvoc 3.5 CFM Vacuum Pump 110V — 1/4 HP Single-Stage, 37.5 Micron Pull-Down, Copper Motor

The Rogvoc 3.5 CFM 110V single-stage vacuum pump is a compact 1/4 HP HVAC tool that pulls down systems to 37.5 microns to remove moisture and contaminants before refrigerant service.

This heavy-duty, single-stage vacuum pump is built for HVAC and automotive refrigeration tasks that require reliable evacuation of air and moisture. Its all-copper motor and reinforced aluminum alloy housing are engineered for durability and heat dissipation, while features like an oil sight glass, dipstick, and an air intake filter help you monitor and protect the unit. Designed for hobbyists and technicians alike, it supports common refrigerants (R12, R22, R134a, R410a) and includes noise-reducing and portability-focused touches.

How quickly and thoroughly does this pump evacuate an HVAC system?

The Rogvoc pump delivers 3.5 cubic feet per minute (CFM) with a 1/4 HP motor, allowing it to reach deep vacuum levels down to approximately 37.5 microns (5 Pa). This performance level is suitable for typical residential and light commercial refrigeration and automotive HVAC evacuation tasks.

• 3.5 CFM flow rate for efficient air removal
• Rated pull-down to ~37.5 microns (5 Pa) for low moisture levels
• Single-stage design: balanced speed with simplicity
• 110V/60Hz power for standard workshop outlets

What durability and maintenance features protect the pump during use?

The unit uses a reinforced aluminum alloy shell for corrosion resistance and effective heat dissipation, paired with an all-copper motor for long life. An internal air intake filter and oil trap help prevent oil backflow and separate exhaust gases to keep internal parts cleaner and extend service intervals.

• Aluminum alloy casing resists corrosion and aids cooling
• All-copper motor increases longevity and reliability
• Oil mist separation and intake filter reduce contamination
• Built-in cooling fan lowers operating temperature and wear

How easy is it to use and monitor oil levels or maintenance needs?

Rogvoc included practical user-focused elements: a sight glass and dipstick let you visually confirm oil level and condition, while an ergonomic handle and low-noise design make transport and operation more comfortable. The sight glass helps prevent overfill or running low on lubricant that can affect pump performance.

• Clear sight glass and oil dipstick for quick oil checks
• Ergonomic handle for simple carrying and positioning
• Low-noise construction for quieter shop use
• Pre-filled at factory; minor transit leaks possible but non-impactful

Which applications and refrigerants are compatible with this vacuum pump?

This pump is suitable for a wide range of vacuum tasks including automotive HVAC service, residential and light commercial refrigeration work, vacuum packaging, vacuum forming, and certain machine maintenance. It is compatible with popular refrigerants and other common HVAC service scenarios.

• Designed for R12, R22, R134a, R410a and similar refrigerants
• Useful for automotive AC, household refrigeration, and HVAC repair
• Also applicable to vacuum packaging and light industrial uses
• Compact footprint fits small workbenches and service carts

Who is this for: The Rogvoc 3.5 CFM 110V single-stage vacuum pump is a practical choice for DIYers, mobile HVAC technicians, and small shop professionals who need an affordable, transportable evacuation tool. It balances performance and portability for routine system pull-downs, maintenance checks, and refrigerant recharge preparation without the complexity or cost of larger industrial units. If you require deeper micron performance or multi-stage drying for large commercial systems, consider a higher-capacity or two-stage model.
