Lowell FW2-KIT-VB KITTWO 4.7" Whisper Fan

Protect sensitive networking, security and surveillance equipment with targeted, low‑noise ventilation. The Lowell Manufacturing FW2‑KIT‑VB KITTWO 4.7‑inch Whisper Fan kit is a rack accessory designed to improve airflow in LWR Series wall‑mount racks, lowering internal temperatures and reducing the risk of thermal shutdowns. Each kit includes two 4.7‑inch fans that deliver 50 CFM of airflow at a quiet 28 dBA, mounted in rugged cast‑aluminum housings with protective fan guards. Magnetic vent blockers let you control intake and exhaust paths to eliminate hot spots and direct cooling where it matters most. Choose a standard power cord or the cord with a built‑in thermostat to automate fan operation based on temperature—ideal for remote monitoring sites, security DVR cabinets, IT closets and small data enclosures. By combining quiet operation, durable construction and simple installation, this Lowell rack fan kit helps extend equipment life and maintain uptime for critical monitoring and surveillance systems. Add the FW2‑KIT‑VB to your rack accessory list to boost cooling efficiency and protect your hardware.
