FAQ

Gast products support a wide range of industries, including food and beverage, industrial manufacturing, health and wellness, laboratory, packaging, printing, and material handling applications. Our technologies are used anywhere reliable air movement, pressure generation, or vacuum performance is required.

An air compressor increases air pressure above atmospheric pressure to deliver compressed air, while a vacuum pump removes air to create negative pressure (vacuum). Many Gast products can operate either as a compressor or a vacuum pump, allowing OEMs and end users to utilize a single platform for multiple functions.

Gast offers both oil-less and oil-lubricated technologies. Oil-less products are commonly selected for applications requiring clean, dry air and minimal maintenance, while oil-lubricated technologies can provide durability and performance advantages in demanding industrial environments.

Selecting the right product starts with understanding your required flow rate, pressure or vacuum level, duty cycle, operating environment, noise requirements, and available power supply.
