Enviro-Vac has introduced a wet injection system to the market, featuring adjustment-free needles.

Compliant with BS 8520-1 & PAS 60-1 the new system has superseded the conventional arrangement of manual flow adjustment at each needle - replacing it with a self-regulating "needle module". 100+ litre fluid reservoir Supplies up to 100 needles Self-regulating needle modules Independent lightweight control box Inside each needle-module is a unique pressure control valve which can deliver a consistent, balanced output of aqueous surfactant to each needle ensuring that the requirements of BS 8520-1 & PAS 60-1 are met. In conjunction with the needle-module a new pumped-surfactant delivery system has been developed, which: Is a robust, durable, all plastic construction. Features a pump capable of reliably delivering fluid even when the injection needles are elevated many meters above the pump unit. Allows needles to be used in any combination up to a maximum of 100 without compromising the flowrate at each needle.
