PRODUCTS – Ventilation Showcase


ABC VENTILATION SYSTEMS ABC Ventilation Systems was founded in 1968 and has grown to become the industry leader in underground ventilation products. ABC’s engineers will design the ventilation system and offer design suggestions to give the best ventilation system at the best price. Our product line consists of fans, ducting, VFD’s, air heaters, cassettes, and deduster systems. ABC’s newest edition to the product line, Hardline Performance Ducting, is a semi-rigid polymer ducting designed to replace steel and fiberglass ducting. With low airflow resistance and low leakage couplings, there is a decrease in energy consumption and number of fans needed for ventilation designs. Hardline is applicable for positive and negative pressure and meets international fire resistance standards. Hardline’s lightweight design allows for a safer and faster installation, and is reusable and recyclable to reflect ABC’s environmentally responsible culture. Hardline ships compressed, which allows for much lower freight costs when compared to other rigid products.
