TWO STAGE VACUUM PUMP - 9.0CFM / (255L/MIN)

Two-Stage Rotary Vane Pump

The core of the pump is a two-stage rotary vane mechanism that achieves a deep vacuum of less than 25 microns, ensuring thorough evacuation of refrigeration circuits, crucial for the optimal performance of air conditioning systems, refrigeration units, and heat pumps.

Solenoid Check Valve

An integrated solenoid check valve prevents the backwash of oil into the refrigeration system during power outages, safeguarding the system from oil contamination and ensuring the purity and efficiency of the refrigeration cycle.

Integrated Vacuum Gauge

The pump features a vacuum gauge with an integrated drag indicator, allowing for simple and quick monitoring of the evacuation process. This enables HVAC technicians to easily control and assess the evacuation status, ensuring precise system preparation.

Durable and Lightweight Casing

Constructed with a light yet high-quality casing, the pump is designed to protect the integrated components from external elements and rough handling, ensuring longevity while maintaining portability for on-site tasks.

Gas Ballast Valve

A gas ballast valve is included to manage the reduction of water vapor in the oil container. This feature is crucial for maintaining the vacuum pump's efficiency and extending its service life by preventing water from compromising the oil's integrity.

Special Oil Mist Filter

To reduce oil mist emissions from the exhaust vent, the pump is equipped with a special filter. This feature contributes to a cleaner working environment and minimizes the release of oil particles into the surrounding area.

Easy Oil Management

The pump is designed with a gauge-glass for easy monitoring of oil levels, facilitating timely refills. Additionally, it features a fast oil filling mechanism without the need for a special funnel, and the oil drain plug is easily accessible for quick and mess-free oil changes.

Thermal Protection Switch

An integrated thermal protection switch prevents motor overheating by automatically shutting off the pump if it reaches a critical temperature, ensuring the safety of the device and prolonging its lifespan.

Versatile Connection Options

Standard 1/4" SAE connection is provided along with adaptors for 5/16" SAE and 3/8" SAE, making the pump compatible with a wide range of refrigeration systems and ensuring flexibility in various HVAC applications.

Removable Power Cable

The inclusion of a removable power cable enhances the pump's durability by preventing cable damage during transport or storage, and it facilitates easy replacement in case of wear or damage.

Ergonomic Design

With an ergonomic handle and compact design, the vacuum pump is easy to carry and operate, making it suitable for HVAC professionals who require a reliable and efficient tool for fieldwork.

Evacuation of Refrigeration Circuits

The primary application of this vacuum pump is the evacuation of refrigeration circuits before the system is charged with refrigerant. This process removes air and moisture from the system, which are critical for preventing corrosion, freezing, and system inefficiency.

Installation and Maintenance of Air Conditioning Systems

The pump is used in the installation and routine maintenance of air conditioning systems. By creating a high vacuum, it ensures that any non-condensable gases and moisture are removed from the system, which is essential for the optimal performance and longevity of air conditioning units.

Servicing of Heat Pumps

Heat pumps, which operate on similar principles to air conditioning systems, also require evacuation to remove air and moisture. The two-stage vacuum pump is ideal for this task, ensuring that heat pumps operate efficiently in both heating and cooling modes.

Preparation of Refrigeration Systems for Repair

Before repairing leaks or replacing components in refrigeration systems, it's necessary to evacuate the system. The vacuum pump is used to ensure that the system is properly prepared for such repairs, minimizing the risk of system contamination.

Moisture Removal from HVAC Systems

Moisture within HVAC systems can lead to a variety of problems, including corrosion, ice formation, and reduced efficiency. The vacuum pump is specifically designed to remove residual moisture effectively, ensuring the system's integrity.

Leak Testing

Following repairs or during routine maintenance, the vacuum pump can be used in conjunction with a leak detector to test the system for leaks. By first evacuating the system, technicians can ensure that any subsequent pressure increase is due to a leak, facilitating accurate leak detection.

Dehydration of Refrigeration Oil

The gas ballast valve feature of the pump allows for the reduction of water vapor in the oil container, which is essential for maintaining the quality and effectiveness of the refrigeration oil used within the system.
