4 CFM Vacuum Pump 110-115V/220-250V Selectable - Robinair

The Robinair 15401 is a professional-grade, two-stage rotary vane vacuum pump meticulously engineered for the thorough evacuation of A/C-R systems. Designed for demanding applications, it effectively removes air and moisture to achieve deep vacuum conditions essential for optimal system performance and longevity. This versatile pump features selectable dual voltage (110-115V/220-250V), making it suitable for various professional environments.

Key Features

• Two-Stage Rotary Vane Design: This robust design initiates the second pumping stage at lower pressures, enabling a deeper ultimate vacuum of 15 microns for complete system evacuation and maximum moisture removal.
• Gas Ballast Feature: Helps maintain pump oil cleanliness by reducing the condensation of moisture, thereby extending the life of the pump and ensuring consistent peak efficiency.
• Iso-Valve™: Allows for quick and easy isolation of the pump from the system with a simple quarter-turn, simplifying rate-of-rise measurements and aiding in system troubleshooting.
• Integral Check Valve: Provides crucial protection by preventing pump oil from being drawn back into the system in the event of an unexpected power loss, safeguarding against contamination.
• Durable Construction: Features a lightweight yet robust die-cast aluminum housing paired with a molded base, which collectively enhance pump balance and minimize operational vibration for a stable workspace.
• Powerful 1/3 HP Motor: Equipped with a heavy-duty, high-torque 1/3 HP motor designed for reliable startup and efficient operation.

Applications

This vacuum pump is specifically designed for evacuating A/C-R systems utilizing common refrigerants such as CFCs, HCFCs, and HFCs, in conjunction with mineral, ester, alkylbenzene, and PAG lubricants. It is not intended for use with ammonia, lithium bromide systems, or flammable refrigerants.
