ROBINAIR 15400 Vacuum Pump, 4 CFM, 2 Stage, 15 Oz Oil Capacity

Robinair 15400 A/C vaccum pump evacuates air and moisture from refrigeration systems, creating a vacuum that ensures optimal performance and efficiency. It is ideal for the automotive, HVAC and food processing industries.

Working Mechanism:

• Robinair 15400 A/C vacuum pump operates by drawing air from the connected system through its intake valves. It uses a 2-stage rotary vane design to compress the air, initially in the first stage and then in the second stage, creating a vacuum within the system.
• To prevent moisture-related issues, the pump employs a gas ballast system that mixes moist air with dry air, reducing condensation risks. Lubricating oil is used to maintain smooth operation and create an effective seal.
• An external exhaust filter separates oil vapour from the expelled air, ensuring oil does not contaminate the evacuated system. The Iso-Valve allows for easy system isolation during maintenance, preventing recontamination.

Features:

• Robinair 15400 A/C vaccum pump features an Iso-Valve mechanism and comes with a gas ballast system that allows moisture-laden air to mix with dry air inside the pump, effectively reducing condensation and preserving system integrity.
• It is equipped with a 2-stage rotary vane design, providing powerful yet quiet high vacuum capabilities, effectively expediting moisture removal and minimising evacuation time.
• This Robinair A/C vacuum pump offers a heavy-duty motor with sealed bearings and high-torque design, ensuring smooth startup and sustained, efficient operation over time.
• This offset rotary vane vaccum pump has an angled oil drain valve for swift and comprehensive oil drainage during maintenance, complemented by a top oil fill port for convenient oil replenishment, simplifying upkeep procedures.
• It is designed with a moulded polycarbonate base, minimising vibrations and ensuring operational balance for consistent performance.

Frequently Asked Questions:

Q. How do I maintain and service this Robinair 15400 A/C vaccum pump?

A. Regular maintenance includes oil changes, checking intake screens and valves for debris and ensuring the gas ballast is functioning correctly.

Q. How does the Iso-Valve feature work?

A. The Iso-Valve allows for quick system isolation with a quarter-turn, preventing air and moisture from re-entering during maintenance.

Q. How does offset rotary vanes improve pump performance?

A. Offset vanes enhance compression, reducing system pressure and improving moisture removal efficiency.
