Weep guns represent a specialized category of high-pressure washing guns engineered with an integrated antifreeze function, making them essential components for outdoor washing installations operating in cold climates. These innovative guns feature a small opening that allows controlled water discharge when the trigger is disengaged, preventing water stagnation inside pipes and protecting systems from freeze damage during particularly low external temperatures.
There are two types of weep guns. We have the "always weeping guns," which allow a small amount of water to flow out when the trigger is released, under all circumstances. Then there are the "low-pressure weeping guns":the distinguishing characteristic of these guns lies in their intelligent pressure-sensitive design. During high-pressure operation, these guns maintain perfect sealing without any leakage, even when the trigger is closed. The weeping function activates only when system pressure drops below 10-15 bar, allowing a few drops of water to continue flowing through the system. This continuous minimal flow prevents liquid stagnation and eliminates the risk of freezing that could damage pipes, connections, and other system components during cold weather conditions.
Weep guns are specifically designed for washing systems installed outdoors and operated by diverse user groups, not necessarily professional operators. The special antifreeze function, combined with compactness and reduced weight, makes weep guns particularly suitable for self-service car wash installations, outdoor municipal cleaning stations, and any high-pressure washing system exposed to freezing temperatures. The user-friendly design ensures safe and reliable operation regardless of operator experience level.
Emiltec's weep gun range accommodates various operational requirements, with models capable of handling pressures up to 310 bar and flow rates up to 30 l/min. These performance specifications make weep guns suitable for professional car washing applications while maintaining the critical antifreeze protection feature. Available configurations include standalone weep guns and complete versions with integrated lances, providing ready-to-use solutions that simplify installation and reduce setup time.
The engineering focus on compactness and low weight makes weep guns exceptionally ergonomic and easy to handle, reducing operator fatigue during extended use. This design philosophy particularly benefits self-service applications where guns must be accessible and comfortable for users of varying physical capabilities. Some models are available in multiple color options, allowing system operators to coordinate equipment aesthetics or implement color-coding schemes for different washing functions.
The weep guns available through Emiltec come from established manufacturers including Mecline and feature robust construction designed to withstand continuous outdoor exposure and frequent use. The combination of reliable antifreeze functionality, durable materials, and ergonomic design ensures long service life even in demanding outdoor environments. Emiltec's technical team provides expert guidance to help identify the optimal weep gun solution for specific outdoor washing system requirements and climate conditions.
