Help protect your vacuum system from oil vapour
This stainless-steel NW25 foreline trap uses alumina to help reduce oil-vapour backstreaming from an oil-sealed vacuum pump. Contact Girovac about fitting it to your system.
Oil vapour can travel back towards the vacuum chamber at low pressure. A foreline trap is used where that contamination could affect an instrument or process.
Tell us about the pump, operating pressure and gases involved. We can discuss trap placement, connection sizes and the heating and maintenance arrangements for this model.
If you are replacing an existing trap, send a photograph and its reference number. Girovac can also help with KF/NW connections and vacuum equipment servicing.
For a quotation or help choosing equipment, contact Girovac or call 01692 660 117.
Parts, consumables and workshop support
Send the pump model and part number when asking about a replacement. Compatibility depends on the equipment and operating conditions.
Before you order
Confirm the exact version, electrical supply and connections. Ask whether oil, filters, fittings, cables or controllers are included or separately specified.
Availability, lead time and the applicable warranty are confirmed for your quotation. A catalogue listing does not reserve stock.
