Atlas Copco’s OSS offers absorption-based condensate management for oil-injected piston and rotary screw compressors below 30 l/s (60 cfm).The oil water separator uses a new, advanced filter medium to remove oil traces to concentrations below 15 ppm1. Easy to install, use and replace, the OSS is the affordable condensate cleaning solution for smaller air systems.
Clean waterAfter separation, oil-in-water concentrations are below 15 ppm
Environmentally friendlyAll materials are 100% recyclable
Economic solutionAvoid collection by a costly third party
Small footprintCompact and lightweight design, optimized for small compressors
Excellent performance thanks to the use of advanced absorption media
Easy installation and replacementA wall or plate mounting bracket is included.
Condensate enters the OSS via the inlet connectionat the top.
Depressurization slits in the top cap allow pressurized condensate to be fed into the separator.
During pre-filtration, the oil-water mixture seeps through polypropylene-based filter media, absorbing and capturing the oil but not the water.
In the post-filtration stage, advanced new filter media absorb the remaining oil.
The anti-siphon vent prevents the separator from completely draining when a flow is passing through the outlet connection.
Clean condensate exits from the outlet with almost no residual oil content.
As a result, the condensate can be discarded into the sewage drain
Our EWD and WD solve all compressed air condensate discharge problems, even with heavily contaminated systems. The water separators and drains offer safe, dependable and economical condensate management. The WD 80 drain valve provides completely automatic drainage of the condensate that collects at the bottom of the air receiver. The EWD drains are electronically controlled, which means they monitor condensate build-up with liquid level sensors and evacuate the condensate only when necessary, to avoid wasting compressed air.
Minimal maintenance, high reliability:
With no moving parts, the water separators offer high reliability while requiring minimal maintenance.
Both automatic and manual drain options are available
The intelligent drain function monitors condensate build-up with liquid level sensors.
It evacuates the condensate only when necessary to avoid wasting compressed air and to generate considerable energy savings
Choose from a wide range:
A wide range of EWD drains is available for oil-contaminated condensate.
This includes models with an additional hard coating for use with oil-free and aggressive condensate
