Gast 1UP-NRV-3A Air Motor

Description

The 1UP-NRV-3A is built for high-RPM tasks (up to 6,000 RPM) where traditional electric motors would be too bulky or pose a spark risk. Because it is powered entirely by compressed air, it is inherently ATEX and CE certified for hazardous locations (Group II, Cat 2), making it safe for environments containing flammable vapors or combustible dust.

A key advantage of the 1UP series is its thermal profile. As compressed air expands through the motor to create rotation, it absorbs heat, allowing the unit to remain cool to the touch even when operating in ambient temperatures up to 121°C (250°F).

Features

NEMA 42C Mounting: Features a compact C-face flange and a 3/8″ (0.375 in) keyed shaft, allowing it to bolt directly to small-frame gear reducers or precision pumps.
4-Vane Configuration: Optimized for high-speed performance and efficient air consumption, offering a balanced power-to-size ratio.
Variable Speed & Torque: RPM can be precisely controlled from 500 to 6,000 RPM by adjusting the air pressure or flow volume.
Explosion Proof: Non-electrical design is ideal for chemical processing, laboratories, and hazardous industrial zones.
Instantly Reversible: A 4-way control valve allows the motor to switch rotation directions instantly, even while running under full load.
Stall-Safe: Can be stalled indefinitely without damage, making it perfect for applications requiring constant tension.
