Securing the operator, respecting sensitive surfaces: whip-check safety, scratch-resistant design
In many industrial environments, pneumatic systems are ubiquitous for powering a multitude of equipment and machinery. However, the use of compressed air under pressure poses inherent risks, notably the risk of whip lash when disconnecting circuits. Whip lash can occur when compressed air is rapidly released from pipelines, creating a sudden and violent force upon disconnection. These accidents can lead to severe, even fatal, injuries for operators and damage to surrounding equipment. Faced with this issue, it is crucial to implement effective safety measures to prevent accidents and ensure a safe working environment for all. It is in this perspective that ISO-C SP40 safety couplers are designed, offering a reliable solution to minimize the risks of whip lash and ensure safe disconnection of pressurized pneumatic circuits.
Scratches caused by pneumatic couplers on sensitive surfaces such as car bodies are a common issue in many automotive workshops and garages. These scratches can result from the interaction between the pneumatic coupler and the surface during the connection or disconnection of pneumatic tools, especially when using paint guns or similar equipment. To solve this problem, several solutions can be considered. First, the use of pneumatic couplers with special coatings or softer materials on the contact surfaces can help reduce the risk of scratches.
Featuring whip-check safety (ISO 4414) and a scratch-resistant design, our new SP40 ISO-C profile safety pneumatic coupler stands out for its lightweight and compact design.
Its body made of fiberglass-reinforced resin and its aluminum swivel base make it a robust, ergonomic, maneuverable, and high-performance solution (flow rate of 1750 Nl/min at 6 bar with an 8 mm passage). Our couplers are thus perfectly suited for environments where surfaces are susceptible to scratches, such as car bodies in automotive garages.
The two-step disconnection (two pushes on the push button) ensures optimal safety for the operator. Indeed, the coupler cannot be disconnected unless the air downstream of the circuit has been completely purged.
