Design and Quality Commitment
Gast is committed to exceptional design expertise, providing customized solutions when standard products do not suffice. The company invests significantly in equipment and personnel to ensure consistent product quality, achieving ISO 9001 certification.

Air Motor Features
Gast Air Motors are versatile, operating in all positions with features like low-shock starts, self-sealing vanes, and mounting flexibility. Available in four-vane or eight-vane models, they include accessories to extend unit life. Key features include variable speed, non-electrical sparking, instant reversibility, cool running, compactness, and minimal maintenance.

Performance Characteristics
Air motors offer variable speed control, with output power and torque dependent on speed and air line pressure. They can be stalled or overloaded without damage and are cost-effective compared to other motors of equal horsepower.

Specifications and Applications
The document details specifications for various air and gear motor models, including operating data, maximum torque, and air consumption. Typical applications include mixing equipment, conveyor drives, pump drives, and packaging machinery.

Safety and Compliance
Gast Air Motors comply with EC directive 94/9EC (ATEX 100a) for use in hazardous atmospheres, designed to prevent static electricity from being an ignition source, making them safe for explosive environments.

Performance Data

Non-lubricated air motors offer up to 0.82 HP with speeds ranging from 500 to 2,000 rpm and a maximum pressure of 80 psi (5.6 bar).
Air consumption and output power vary with speed and pressure, as depicted in the provided graphs.

Product Dimensions

Dimensions provided in both inches and millimeters for various mounting configurations.

Air-Powered Gear Motors

Advantages over electric motors include more horsepower, speed control, flexibility, configurations, and longer life.
Gear motors are available in four mounting configurations and are non-electrical sparking, suitable for explosive environments.

Warnings

Gast Air Powered Gear Motors are not self-locking. For applications requiring a brake for safety in case of air pressure failure, contact the distributor.

Overview This document provides technical specifications, features, and recommendations for various models of Gast Air Motors and Gear Motors. It includes detailed information on gear reducers, mounting options, recommended accessories, and performance metrics such as torque, horsepower, and air consumption.

Specifications The document outlines specifications for different models, including gear reduction ratios (20:1 and 40:1), torque ranges, and speed outputs. It also specifies the maximum allowable end thrust and overhung load for the output shaft.

Features Key features include base mounting, optional mountings and shaft locations, and the use of mufflers. The document also lists recommended accessories such as filters, regulators, gauges, lubricators, and repair kits.

Performance Metrics Graphs illustrate the relationship between speed (RPM) and output power (horsepower and kilowatts), torque (lb.in and Nm), and air consumption (CFM and l/s) at various pressures (20 psi to 100 psi).

Product Dimensions Detailed dimensions are provided for each model, including mounting options and shaft locations. Measurements are given in both inches and millimeters.

Accessories The document includes information on filters, regulators, lubricators, gauges, and mufflers, specifying their part numbers, port sizes, flow rates, and dimensions. It also mentions the necessity of using an air pressure regulator and filter for efficient operation.

Installation and Maintenance Instructions for foot assemblies for air motors and gear motors are provided, emphasizing fast and simple installation. The document also highlights the importance of using the correct oil type for lubrication.

Air Motors/Gear Motors, Lubricated and Non-Lubricated-3

Variable Speed You can vary air motor speed between 300 and 10,000 rpm (depending on model selection) with a simple valve put in between the air source and air motor. Non-electrical Sparking As a non-electrical device, the possibility of explosion from igniting flammable gases is greatly reduced. Instantly Reversible A four-way valve in the air line enables a Gast Air Motor to be instantly reversed. A turn of the valve causes a complete reversal of rotation, even when the motor is running at full speed. Cool Running As the air motor turns, expanded air cools the motor. Units can be used in ambient...
