When the Balsan Group of Johnstone Supply purchased space in Waldorf, Maryland, for its seventh branch office, the group’s Technical Service Advisor was charged with designing the HVAC system.
These 500-W, 230-V, single-phase electronically commutated (EC) motors are available on Rosenberg’s axial- and backward-curved fans for HVAC and equipment cooling applications.
Suitable for air temperatures up to 140°F, the fan can exercise automatic rest thermal overload protection. A permanently lubricated ball bearing motor allows for maintenance-free operation.
This model can be specified with either a Vari-Green® EC (electronically commutated) motor with a speed control dial for single-phase motor applications or a NEMA premium efficiency motor with a factory-mounted variable frequency drive (VFD).
These axial transfer fans provide ventilation for ductless underground parking applications. In a ductless system, the garage still uses a main supply and exhaust duct, but the installation of an axial transfer fan eliminates the need for ductwork throughout the parking areas.
MINNEAPOLIS – Twin City Fan Companies announced a price increase for Twin City Fan & Blower. Pricing for most Twin City Fan Companies products and programs will increase globally between six and nine percent, varying by country and product. The increase will be effective immediately.
