RA 15401
Cooltech™ Vacuum Pump – Capacity 93 l/min
The purpose of a vacuum pump is to remove moisture and air from an A/C-R system. Modern systems are built tighter and charges are more critical. That means these systems have a greater sensitivity to moisture and other contaminants, making thorough evacuation more important than ever before. Moisture in a refrigeration system, directly or indirectly, is the cause of most problems and complaints. First, moisture can cause a freeze-up in a system. Moisture is picked up by the refrigerant and transported through the refrigerant line in a fine mist, with ice crystals forming at the point of expansion. A "freeze-up" is not the only problem caused by moisture. It can also result in corrosion, the effects of which are not apparent until the real damage has occurred. Moisture alone is bad enough, but combined with refrigerants containing chlorine, hydrochloric acids can form. These greatly increase the corrosion of metals. Also, refrigerant oil rapidly absorbs moisture. Water-formed acids combine with the refrigerant, forming a closely bonded mixture of fine globules. The effect is called sludging and it greatly reduces the lubricating ability of the oil. A vacuum pump removes troublesome moisture by lowering the pressure within the system and vaporizing (or boiling off) the moisture, then exhausting it along with air.

Description
Makes adding oil simple since the port is accessible from the front or either side. The sight glass on the front of the pump shows you when enough oil has been added.
High torque design for easy startup and
efficient operation.
Our proven design builds a powerful compression within the pumping chamber to reduce system pressure and vaporize moisture so it can be exhausted along with air.
Durable polycarbonate base improves pump balance and minimizes vibration during operation.
Moisture laden air passing through the pump mixes with relatively dry air to such a degree that compression does not cause condensation.
Isolates the pump from the system with just a quarter-turn.
Cast aluminium housings make the pumps lightweight but durable.
Cleans the system more thoroughly than a single-stage pump; the second stage starts pumping at a lower pressure so you can pull a deeper, ultimate vacuum.
Positioned at the bottom of the oil reservoir and angled for faster, more complete draining.
