Sight glass wiper type SGW with double wiper blade

The SGW type sightglass wipers are designed for manual cleaning of glass plates in circular sightglass fittings. They are designed for applications in pressure or vacuum operation and can also be retrofitted in existing sightglass fittings.

Our sight glass wipers are made of high-quality stainless steel and are also suitable for the food sector. For the wiper blade material, you have the choice between blades made of PTFE, silicone or EPDM.

Sight glass wipers of the SGW type are particularly effective in combination with the SVI spraying device.
