Fischer Expanding Foam Applicator Gun

The Fischer Expanding Foam Applicator Gun is a professional-grade foam gun designed for applying one-component expanding foam on construction sites and building projects. Its compatibility with all standard canister systems makes it a versatile choice for contractors, builders, and tradespeople working with PU foam products. Engineered with a lightweight construction, the gun reduces hand and arm fatigue during extended periods of use — particularly useful on busy sites where productivity matters. The design prioritises ease of handling without compromising control or performance. A key safety feature is the impact-requiring control mechanism, which prevents the regulating screw from being accidentally loosened during operation. This ensures consistent foam flow and reduces the risk of unintended application. When work is interrupted, opened canisters can remain attached to the gun without the foam curing, saving time and reducing material waste.
