Dayton 7DJ40 30" Non-Oscillating Blower 115VAC 8900 CFM
30-inch stationary blower moves 8900 CFM on 115 VAC with a 1/2 HP direct-drive motor rated for 140 °F ambient temperature
- Moves 8900 CFM for rapid air exchange in large spaces
- Operates at 140 °F ambient for high-heat industrial environments
- Direct-drive 1/2 HP motor reduces maintenance with no belts
- 75 dBA sound level suits noise-sensitive work areas
- Mounts on I-beam or post for flexible installation
30-Inch High-Temperature Blower
This Dayton 7DJ40 air circulator moves 8900 CFM at 115 VAC for industrial environments that reach 140 degrees Fahrenheit. Its 30-inch steel blade and direct-drive half-horsepower motor run at a single speed of 1075 RPM while drawing 4.9 amps. The non-oscillating frame mounts on I-beams or posts and measures 33 inches wide by 33 inches high by 14-1/4 inches deep.
Replaces Smaller or Lower-CFM Units
When a facility needs more air movement than a standard shop fan provides, the jump to 8900 CFM and a 140-degree ambient rating is worth it. The 350-watt motor delivers 700 feet-per-minute velocity at 20 feet without oscillation mechanics that can fail in high-heat settings. One fixed speed simplifies wiring and reduces maintenance points compared with multi-speed alternatives.
Suits Fixed High-Heat Installations
This blower suits plants, foundries and equipment bays where a stationary, high-ambient fan must bolt directly to structural steel. Operations that require variable airflow, oscillation, portability or lower noise than 75 dBA should look at something else. Buyers needing a different voltage, phase or mounting style will also need another solution.

Questions about this item
What mounting locations does the 30" blower support for the I-beam or post installation?
The fan is designed for mounting on an I-beam or post using the stationary frame; no oscillating hardware is included.
Which wiring step is most often missed when connecting the 115V AC, 4.9-amp motor?
Connect the single-phase 115 V supply to the motor leads and verify the 60 Hz rating matches the site power before energising.
When should the 1/2 HP direct-drive motor bearings be inspected on a unit running at 1075 RPM in 140 °F ambient?
Inspect bearings annually or after 2 000 operating hours; high ambient temperatures can accelerate grease breakdown.
