Commercial Ventilation

The second half of the 20th century brought with it new realizations of the importance of air quality and the need for proper ventilation of working spaces, in order to meet increasing demands for more healthy working conditions, as well as new, regulated, work place safety standards.

The post World War II market responded with a new generation of low cost, light weight panel style, wall fans, in a range of sizes, powered by a new mid 20th century generation of FHP electric motor technology.

Fans were typically equipped with automatic louvers, electric thermostats and electric motors with state-of-the-art automatic overload protection, all as optional features, appealing to the increasing expectation for automated everything.

Small ventilation fans and accessories were supplied to the trade through a growing number of equipment and parts wholesalers serving the HVACR industry in Canada.

To be found installed throughout the later 20th century in food stores, restaurants, butcher shops, as well as in garages, work shops and small industrial applications, as a low cost and affordable alternative to air conditioning.
