[27102 OSH] Prevost Blow Gun with Venturi & Dead-End Nozzle

The Brüder POWER FULL Air Blow Gun OSH (27102 OSH) is a professional compressed-air cleaning tool designed for high efficiency, controlled output, and enhanced operational safety. This variant is the most popular configuration in its class thanks to its OSHA-style composite nozzle, which limits outlet pressure while maintaining excellent blowing performance. It is particularly well suited to industrial, automotive, fabrication, woodworking, and maintenance environments where safe use of compressed air is a priority.
The body of the blow gun is manufactured from a durable polyamide composite that offers high impact resistance while remaining lightweight and comfortable for extended daily use. The non-scratch housing helps prevent accidental marking of surrounding surfaces, fixtures, or finished components, making it suitable for both heavy-duty workshop tasks and more delicate cleaning applications. An ergonomic grip and smooth trigger action allow precise modulation of airflow, giving the operator excellent control from light dust removal to more forceful clearing.
The defining feature of the OSH model is its composite safety nozzle with side relief ports. These lateral openings are primarily designed to prevent dead-end pressure build-up if the nozzle is blocked, significantly reducing the risk of injury and equipment damage. In practical use, the side ports also create a subtle venturi effect, entraining surrounding air into the main jet. This increases the effective cleaning volume while keeping outlet pressure limited, resulting in strong real-world performance with lower air consumption.
At a typical operating pressure of 6 bar, the blow gun consumes approximately 13 Nm³/h of air, making it highly efficient compared to traditional open nozzles. The outlet pressure is limited to around 2 bar, with a dynamic pressure of roughly 1.2 bar measured at 10 mm from the nozzle. This balance of safety and effectiveness is one of the key reasons this configuration is a best seller. Noise levels are approximately 90 dBA, appropriate for industrial use when standard hearing protection is worn.
With a blowing force of approximately 270 g and an elbowed nozzle length of 69 mm, the OSH blow gun provides good reach into confined spaces such as machine enclosures, engine bays, cabinets, and workpiece recesses. The angled nozzle improves visibility and access while keeping the user’s hand clear of debris and airflow.
Typical applications include clearing swarf and chips from machined parts, cleaning workbenches and production lines, drying components after washing, removing dust from filters and housings, and general workshop housekeeping. The pressure-limiting safety nozzle makes it especially suitable for shared workspaces, training environments, and operations with strict safety policies.
As part of the Brüder POWER FULL Air range, the 27102 OSH reflects a focus on dependable performance, operator safety, and long service life. It delivers the controlled airflow professionals expect, combined with a safety-oriented nozzle design that has made it a trusted everyday tool across a wide range of industries.
