Vacuum Degassing Chamber - 26L

Please note in a revision the lid now no longer includes handles. See notes below.

A professional workshop/studio quality degassing chamber is an invaluable piece of equipment for anyone working regularly with RTV silicone rubber or casting/laminating resins including polyurethane, epoxy and polyester. Degassing silicones is essential to create accurate, tear resistant moulds free from surface defects such as trapped air bubbles.

The chamber features a heavy-duty powder-coated steel construction. The custom-designed silicone seal quickly and securely locates the laser-cut clear acrylic lid ensuring perfect closure.

The chamber is supplied complete with vacuum gauge, adjustable soft-release valve and all necessary fittings to connect directly to any standard vacuum hose.

Full set of spares available.

Recommended Vacuum Pumps

The DC26 degassing chamber does not include a vacuum pump.

For low reactivity materials such as RTV silicone rubber, a standard compact vacuum pump such as our ECVP425 Composites Vacuum Pump empty the chamber down to 90% vac in around 1m 45s and full vacuum in around 4 minutes and be perfectly adequate.

For more reactive materials where it is important to complete the degassing as quickly as possible we would recommend a high capacity vacuum pump (10CFM+) such as our 12CFM ECVP4300 High Capacity Composites Vacuum Pump which can pull the chamber down to 90% vacuum in 30 seconds and full vacuum in 1m 30s.

Vacuum Pull-Down Times

The table below shows the time taken for two different capacity pumps to reach various levels of vacuum in the chamber

Table above for information only and times based on Easy Composites' two vacuum pumps. Times for other makes and models will vary.

Revised Model

Following customer feedback we have recently updated our vacuum degassing chamber to remove the handles from the lid. This is in response to some issues with the handles coming loose after frequent degassing operations where the vacuum pressure flexing the lid eventually weakened the bond. The lid can still be easily removed by lifting it at the edges in common with most other degassing chambers. The removal of the handles has also enabled us to reduce the price of the chamber.
