ATTACHMENT 8 - FAN INSPECTION RECORDS.pdf

This document is a series of exhaust fan inspection reports prepared by Mission Aire Corporation for Tibor Rubin VA Medical Center in Long Beach, California, dated August 12, 2023.

The inspections cover multiple exhaust fans across Buildings #150, #126, #138, #164, and #1, with locations spanning the 3rd, 11th, and 5th floors. General inspection and maintenance was scheduled for May 2, 2024, with filter change dates set for July 31, 2024 (or July 9, 2024 for some units). The fans inspected range from 1 to 5 horsepower motors with frame sizes of 143T, 145T, or 184T, operating at various voltages and RPMs between 1,725 and 3,510. Belt types and quantities vary by unit (AX24, AX26, AX29, AX32, AX36, AX52, 4L-310). The primary action item across all units is belt replacement. Additional maintenance includes blower bearing greasing (marked "Yes" for all units) and entering/leaving duct work inspection. Several fans have variable frequency drives manufactured by Yaskawa, with notes indicating keypads are blank and should be replaced, with possible additional repairs required. Pre-filter and final filter magnetic pressure gauges are documented with recorded measurements in inches of water where applicable. Equipment-specific issues noted include one unit with a non-functioning magnetic gauge requiring replacement, another with high voltage power issues, and filter door bolting deficiencies addressed on July 25, 2024.
