Test Report

Object: To measure air delivery in CFM and sound level in DB according to NEMA standards, and to measure the guard spacing, angle of tilt, and height of industrial pedestal fans, model JF-PF20-2SP, JF-PF24-2SP, and JF-PF30-2SP.

Description and Observations:

(A) Air Delivery – Taken at 2 ft. Test specifications: NEMA Std. Pub. No. FM 1; para. FMI – 6.04.

1. Model JF-PF20-2SP steel blade, measured CFM is 4250 on high speed
2. Model JF-PF24-2SP steel blade, measured CFM is 6210 on high speed
3. Model JF-PF30-2SP steel blade, measured CFM is 7710 on high speed

(B) Noise Level: Test specifications: NEMA Std. Pub. No. FM 1; para. FMI – 6.08

1. Model JF-PF20-2SP steel blade, measured average noise level is 60.2 db on high speed
2. Model JF-PF24-2SP steel blade, measured average noise level is 64.0 db on high speed
3. Model JF-PF30-2SP steel blade, measured average noise level is 70.9 db on high speed

(C) Tilt Adjustments: The following adjustments are possible:

(D) Height: All three models have a height of 5' at the center of the blade.

(E) Guarding: The fan guards meet the requirements of the State of Michigan, Department of Labor, Safety Standards for Guards and U.S. Department of Labor, Federal Safety Standards, Occupation of Safety and Health Act. Guarding Spec. 1910.218, and Underwriters' Laboratory Standards No. 507, para. 27.6
