Degassing kit for resin and lab use

This kit pairs a 3.5 CFM single-stage pump with a 3 gallon stainless steel chamber and acrylic lid for degassing resin, silicone and epoxy. The pump reaches an ultimate vacuum of 5 Pa and uses a four-stage pure copper motor with a built-in cooling fan. A 4.92 ft hose, gauge, shut-off valve and silicone pad are included. The unit weighs 20.11 lbs and the pump measures 10.83 x 4.72 x 8.86 in.

Suited for hobbyists and small workshops needing

The transparent acrylic lid lets you watch bubble removal in real time, which helps when learning resin casting or silicone mould making. The 3 gallon capacity limits batch size, so users processing large volumes or running continuous production should consider larger chambers. The kit is not suitable for wood stabilization, and the single-stage pump will not reach the deeper vacuum levels some scientific protocols require.

Bundled accessories enable immediate operation

The supplied 330 ml bottle of vacuum pump oil fills the 0.27 qt reservoir so the pump can run straight away. A toolbox with wrench and intake filter simplifies routine maintenance, while the red and blue manual shut-off valve gives direct control over vacuum hold. The gauge, hose and silicone pad complete the plumbing without extra purchases.

Questions about this item

Do I need to supply my own vacuum pump oil before first use?

The kit includes a 330 ml bottle of vacuum pump oil, and the pump holds 0.27 qt (260 ml), so no extra oil is required to start.

Will the 1/4" SAE intake fitting connect directly to my existing vacuum hose?

The included 4.92 ft hose terminates in a 1/4" SAE fitting that matches the pump intake; other hoses need the same thread to connect.

How can I verify the pump is reaching its rated vacuum level after setup?

Watch the supplied vacuum gauge; it should indicate a deep vacuum approaching the pump's 5 Pa ultimate rating once the chamber is sealed and the pump runs.
