RAB SWISHAIR2X2/PIR/E SWISH AIR LED Troffer — 35W/26W/18W Selectable — 3500K/4000K/5000K — PIR Sensor — Battery Backup — White The RAB SWISHAIR2X2/PIR/E is a 2×2 recessed LED air-return troffer with a factory-installed Passive Infrared (PIR) occupancy sensor and integrated 90-minute emergency battery backup, designed for commercial T-grid ceilings requiring HVAC return-air functionality, occupancy-based energy control, and life-safety code compliance. Wattage is field-selectable between 35W (factory default), 26W, and 18W, and CCT is field-selectable between 3500K, 4000K (factory default), and 5000K — both via onboard switch, no tools required. At peak output, the fixture delivers 4,703 lumens at 35W / 4000K with a peak efficacy of 146.4 lm/W at 18W / 4000K. The SWISHAIR2X2/PIR/E operates on 120–277V with a 0–10V dimming driver and is UL Listed for dry and damp locations and DLC 5.1 Listed as Ultra-Efficient Premium. Replaces conventional fluorescent 2×2 troffer fixtures. Key Features Selectable Wattage: 35W / 26W / 18W — field-adjustable via built-in onboard switch, factory default 35W. No tools required.

Rated life 100,000 hours (L70) per IES LM-80 / TM-21. Smart & Control Features The SWISHAIR2X2/PIR/E includes a factory-installed PIR occupancy sensor, 0–10V dimming, and integrated 90-minute emergency battery backup. The PIR sensor detects occupancy via heat differential and requires direct line of sight — ideal for open-plan spaces without partition obstructions. The battery backup activates automatically on power failure, maintaining illumination for safe egress. Battery Backup Light Loss Factor: 0.18. Requires an unswitched hot line to maintain charge.
