Triangle’s “FHIR” series industrial-grade true reversible exhaust and supply wall fans come in belt or direct drive models and are ideal for applications that have supply or exhaust needs out of the same fan. Triangle “FHIR” industrial-grade reversible wall fans come with a true, bi-directional venturi and bi-directional airfoil blades. The combination of the bi-directional venturi and blades prevents the traditional loss of performance associated with other “reversible” fans. The FHIR true reversible fan is the highest performing reversible supply and exhaust fan available on the market.
