Centrifugal Blower Fan PreAsion PP250 110V Exhaust Fan 300W/1450RPM

Description

Product Overview

The PreAsion PP250 is a high‑efficiency centrifugal blower fan engineered for demanding laboratory and industrial environments. Constructed with a corrosion‑resistant polypropylene (PP) shell and a lightweight ABS impeller, the fan combines durability with ease of handling. It delivers a maximum airflow of 1350 cubic feet per minute (CFM) at a power consumption of 300 watts, achieving an impressive efficiency of 4.5 CFM per watt. Operating at a speed of 1450 RPM, the fan maintains a low noise level of 40 decibels, ensuring a quiet workspace. The unit is designed for 110 volt corded electric power and features a tabletop mount installation, making it suitable for both indoor and outdoor applications. Additional specifications include three selectable speed levels, touch control, and a thermal overload protection system that extends motor life up to 50,000 hours.

Usage

Designed with versatility in mind, the PP250 excels in a variety of ventilation scenarios. It is an ideal solution for laboratory fume hoods, where rapid extraction of hazardous fumes, gases, and particulates is critical for safety and compliance. The fan’s robust construction also makes it suitable for chemical cabinets, providing reliable protection against corrosive vapors. Outdoor installations benefit from the fan’s weather‑resistant housing, allowing it to serve as an exhaust unit for workshops, warehouses, and greenhouse environments. The three speed settings enable users to tailor airflow to specific tasks, whether it is a gentle circulation for odor control or a high‑speed purge for emergency situations. Its compact dimensions (18.5 × 18.4 × 18 inches) and lightweight design (20.4 lb) facilitate easy transport and quick setup, reducing downtime during equipment changes or maintenance.
