RadonAway High Suction Fan Variable Wattage (HS2750) with 4 Speed Settings
RadonAway's HS2750 is an ETL-listed high suction blower designed for professional radon mitigators tackling challenging installations. Multiple speed settings meet site-specific pressures and airflows, easily verified by the built-in magnehelic pressure gauge on the front cover. A new electrical box design with wire terminal strip and two included flexible pipe couplings make for quick, clean site installation.
- 4 blower speed settings (Low, Medium, High, Maximum).
- Built-in 40" magnehelic vacuum gauge confirms system operation.
- Integrated condensate bypass protects motor from moisture.
- Quiet operation; single-stage blower designed for harsh environmental conditions.
- Designed for easy motor replacement.
- Thermally protected — shuts off at 185°F / 85°C; auto-restarts below 75°C.
- Locked rotor protection.
- ETL Listed; conforms to UL STD. 507 and CAN/CSA STD. C22.2 No. 113.
- Not compatible with solid state speed controls.
