McGill AirPressure offers the following equipment and services:

  • Autoclaves, including those used in the manufacture of advanced aerospace composite materials. We have supplied some of the world’s largest and most advanced autoclave systems. McGill AirPressure pioneered a practical, small autoclave system for use in laboratories and with small process applications. This Mini-Bonder™ autoclave is used by companies developing and producing CRT screens, safety and architectural glass, and bonded circuit boards.

  • Vacuum Dryers, including rotary, shelf, conical, and chamber types, for processing materials that are sensitive to heat, and susceptible to oxidation, or release hazardous gases into the atmosphere during the drying process. These dryers are used in the chemical, pharmaceutical, and food and beverage industries.

McGill AirClean offers the following equipment and services:

  • Electrostatic Precipitators (EPs) are used for the control of particulate emissions in a variety of industries. Applications include coal- and wood-fired boilers, wood dryers, glass-melting furnaces, steel-making processes, chemical recovery furnaces, and lime and refractory kilns. Using McGill AirClean’s unique designs, these high-efficiency precipitators enable numerous industries to meet today’s clean air standards.
