Orion Motor Tech 4.5 CFM Vacuum Pump & AC Manifold Kit, Blue — 1/3 HP Copper Motor

Orion Motor Tech’s OMT 4.5 CFM kit is a complete AC evacuation and charging set that pairs a 1/3 HP vacuum pump with a four-way manifold, leak detector, hoses, adapters and tools to service R134a, R22 and R410a systems.

This all-in-one kit brings professional-style HVAC service gear into a portable case designed for automotive and small residential jobs. The package combines a high-flow 4.5 CFM vacuum pump built around an all-copper motor with a precision 4-way manifold gauge, heavy-duty color-coded hoses, R134a can taps, R410a adapters, a handheld electronic leak detector, and vacuum oil so you can start work immediately. Components are arranged in a rugged carrying case for organized transport and storage.

How quickly does the 4.5 CFM pump evacuate an AC system?

The 4.5 CFM rating indicates a high evacuation rate for a 1/3 HP pump, helping to remove moisture and non-condensables faster than lower-CFM units. The all-copper motor improves torque and heat tolerance while the aluminum alloy housing dissipates heat for longer continuous runs.

• 4.5 cubic feet per minute flow for faster pull-downs
• All-copper motor for consistent performance
• Aluminum alloy casing for rapid heat dispersion
• Tethered brass caps prevent oil drips during transport

What gauges, hoses and adapters are included, and are they durable?

The kit includes a 4-way manifold gauge set with color-coded hoses rated to 800 psi working pressure and 4,000 psi burst pressure, giving a high safety margin for charging and pressure checks. The manifold supplies clear analog readings for service tasks and the quick-coupler taps and R410a adapters let you connect to common refrigerant sources.

• Four-way analog manifold for high/low and service port control
• Color-coded 4-layer hoses for visibility and toughness
• R134a can taps and R410a adapters included for immediate use
• Quick couplers streamline hook-up and reduce leaks

Does this kit include accessories to diagnose leaks and maintain the pump?

Yes — a handheld electronic leak detector is included to help locate refrigerant leaks before evacuation and charging. The vacuum pump features an oil sight glass, bottom drain valve for easy oil changes, a cooling fan for extended operation, and a supply of vacuum oil to reduce setup time.

• Electronic leak detector for fast refrigerant source location
• Oil sight glass and drain valve for simple maintenance
• Built-in cooling fan to prevent overheating during long runs
• 0.26 qt vacuum oil included so the pump is ready to use

Which refrigerant types and systems can I service with this kit?

The components are compatible with common service refrigerants R134a, R22 and R410a, making the kit suitable for automotive air conditioning, home split systems, window units and a range of residential HVAC work. Adapters and can taps are supplied to handle typical service scenarios without extra purchases.

• Works with R134a, R22 and R410a refrigerants
• Includes R410a adapters and R134a can taps for flexibility
• Suited for cars, mini-splits, home AC units and small HVAC systems
• Components store neatly in the included carrying case

Who is this for: The Orion Motor Tech OMT 4.5 CFM AC Vacuum Pump and Gauge Set is aimed at automotive technicians, HVAC contractors, and experienced DIY homeowners who perform system evacuation, leak localization and refrigerant charging. It’s a practical choice when you need a portable, ready-to-use toolkit that combines a powerful vacuum pump with precise gauges, durable hoses and the adapters required for modern refrigerants. If you need faster evacuation, clear pressure diagnostics and immediate leak-testing capability in a single case, this kit delivers core tools without requiring separate purchases.
