Soler Palau SDB15RH1S Belt Drive Roof Exhauster 15 in 3375 Cfm

Product Description

The SOLER PALAU SDB15RH1S is a downblast belt drive centrifugal roof exhauster designed for continuous-duty commercial ventilation. It uses a 15-inch backward inclined wheel spinning at 1450 RPM to deliver up to 3375 CFM at zero static pressure, with a maximum static pressure capability of 1-1/4 inches WG. The 3/4 horsepower motor is available in 115, 208, or 230 volt configurations — voltage must be specified at time of order. Belt drive reduces operating RPM and noise levels compared to direct drive units, making this exhauster suitable for occupied commercial spaces where sound is a factor. The housing is built for heavy-duty, continuous use and includes a birdscreen, stainless steel exterior fasteners, and a disconnect. A licensed HVAC technician or mechanical contractor handles installation.

The SDB15RH1S is intended for commercial facilities requiring removal of relatively clean exhaust air. It installs on the roof curb, positioning the unit close to the ventilated area to allow shorter duct runs and more efficient system performance. It is compatible with both ducted and non-ducted applications. The single-speed open drip-proof motor is accessible by removing the housing cover, simplifying routine maintenance. An optional factory-installed automatic belt tensioner (part 100070) is available to prevent over-tensioning of drive components and must be ordered at the time of the unit purchase.

Key Features

• 15-inch backward inclined wheel delivers 3375 CFM at zero static pressure
• Belt drive design reduces operating RPM to 1450 and lowers sound output to 18.8 sones at 1/4-inch SP
• Multi-voltage motor available in 115, 208, or 230 volts — specify at time of order
• AMCA Air and Sound Licensed and UL 705 Listed for verified performance and safety compliance
• Removable cover provides direct access to motor for maintenance without specialty tools
• Stainless steel exterior fasteners, integrated birdscreen, and disconnect included standard

Compatibility

The SDB15RH1S is a direct replacement-style option for Greenheck GB, Loren Cook ACEB, Pennbarry DX, Carnes VEBX, Acme PRN, and Fantech 5BDD series belt drive downblast roof exhausters.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor following applicable mechanical and building codes. Disconnect and lock out all electrical power before servicing the motor, belt, or drive components. The unit mounts on a roof curb sized to the 19.5-inch roof opening dimension — verify curb compatibility before installation. Do not over-tension the belt; if automatic tensioning is required, the factory-installed 100070 tensioner must be ordered with the unit and cannot be added in the field.
