PB Motor Tech BMT 4.5 CFM Vacuum Pump & Aluminium Manifold Gauge Set, Green — 1/3 HP Compact Kit

The PB Motor Tech BMT 4.5CFM Vacuum Pump & Aluminum Manifold Gauge Set is a complete HVAC/R evacuation and charging kit that pairs a 4.5 CFM vacuum pump with a durable aluminum 3-way manifold and accessories for rapid, reliable refrigerant service.

This compact green kit combines a 4.5 CFM, 1/3 HP vacuum pump with an aluminum alloy manifold gauge set and color-coded hoses to support evacuation, leak detection, charging, and basic diagnostics on automotive and residential refrigeration systems. Built for technicians and experienced DIYers, the package balances lightweight construction with corrosion-resistant materials and practical features—like a sight glass on the oil tank, non-slip handle, and included adapters—so you can work efficiently across multiple refrigerants.

How quickly will this pump evacuate a system?

The 1/3 HP motor provides a rated flow of 4.5 CFM, allowing fast evacuation of small to mid-size systems. Flow rate and actual evacuation time depend on system volume, leak tightness, and target vacuum level.

• 4.5 CFM flow for quick pull-downs on typical automotive and home units
• Aluminum housing for consistent heat dissipation during continuous use
• Inlet filter to reduce oil backflow and prolong pump life

What does the manifold gauge set include and how is it useful?

The aluminum 3-way manifold provides clear pressure readings and service ports for high, low, and charge lines. The kit bundles essential accessories so you can measure, recover, and recharge refrigerant without hunting for extra parts.

• 3-way aluminum manifold with rubber-coated large dials for readability
• Three 4-foot color-coded hoses (high, low, charging) rated 600 psi working, 3000 psi burst
• Adapters and taps: R134a quick couplers, R410 adapter, puncturing and self-sealing can taps, valve core tool
• Includes pump oil and sight glass for monitoring oil level and condition

Which refrigerants and systems are compatible with this set?

This kit supports a broad range of common refrigerants and is suitable for HVACR maintenance on vehicles and household equipment. It’s designed to handle R134A, R410A, R22, and R404A, making it versatile for many diagnostic and charging tasks.

• Compatible with R134A, R410A, R22, and R404A refrigerants
• Useful for automotive A/C, small residential systems, and refrigeration service
• Adapters and quick couplers included for fast connection to service ports

How does the pump and manifold stand up to everyday jobsite wear?

Materials and design focus on durability and practical handling to withstand frequent use. The aluminum manifold resists corrosion while the pump’s construction helps dissipate heat; rubber feet and a non-slip handle keep operation steady and transport safe.

• Aluminum alloy manifold and pump housing for corrosion resistance and lower weight
• Rubber-coated dials and transparent sight glass for clear monitoring and grip
• Rubber isolation feet reduce vibration and noise during operation

Who is this for? If you are a professional HVAC technician, mobile A/C specialist, or a knowledgeable DIYer performing regular refrigeration or automotive A/C maintenance, this PB Motor Tech BMT set provides a compact, all-in-one solution. It’s best suited for routine evacuation, leak diagnosis, and refrigerant charging on small to medium systems where portability, corrosion resistance, and a complete accessory bundle matter. For large commercial systems or specialty refrigerants, consult equipment specifications and local regulations before use.
