Silvent 500-L

SILVENT 500-L: with a stainless steel Laval nozzle. A Laval hole in the center of the nozzle creates a highly concentrated air stream that moves at supersonic speed. Around the Laval hole there are also a number of diverging slots that generate a powerful, quiet and laminar air flow. The combination provides superior cleaning performance and optimal utilization of the compressed air. Fins prevent direct contact between skin and the outlet holes. Blowing force 4.2 N (14.8 oz).

No muscle strain
The trigger mechanism requires a pressure of only 7 N (25 oz), which means that the gun can be used frequently without the risk of taxing muscles. The average finger strength of men is 96 N (339 oz) and of women, 81 N (295 oz). When less than 10% of the maximum strength of a finger is used, no injury arises due to muscle strain.

Ergonomics and precision
The combination of an ergonomic handle and a short trigger for one or two fingers provides a perfect grip as well as the possibility to aim the gun with precision and feeling. The ergonomic design of the handle automatically gives you the optimal blowing position so that you do not need to bend your wrist.

Our safety guns are fitted with short triggers as standard to provide the most ergonomic grip. If desired however, they can also be equipped with extended triggers.
