RL-4

4661741

2-stage vacuum pump free air displacement: 65 l/min, connections 1/4" SAE + 3/8" SAE, oil capacity: 250ml

The lightweight workhorse among the high-performance vacuum pumps in the REFCO range. High-quality components and sophisticated technology maintain the high performance of the two-stage rotary vane pump even under maximum load, so that the desired deep vacuum is reached faster.

Send in your used pump: we will overhaul it at a flat rate! Thus your vacuum pump purchase becomes a long-term investment in a quality tool!

Low weight and highest quality thanks to the use of high-quality materials
Gas ballast valve
Internal oil circulation for optimum lubrication
Easy reading of the optimum oil level (sight glass middle)
Large oil filler neck for easy and clean filling of oil
Special filter reduces oil mist at the blow-out nozzle
Stable and ergonomic handle
Integrated on/off switch against damage and unintentional operation

This is the question!!
Hello, how are you?
coreshop.ui.product.faq.copy_link
What's the purpose of gas ballast valve in RL pump?
It serves to releasing the moisture coming with evacuated air to reduce oil pump contamination.
