Recommendation
This Captive-Aire Commercial High Speed Upblast Exhaust Fan directly matches your criteria: it’s the CaptiveAire brand you requested and is listed at $739.90, comfortably within your $1,500 budget. The unit’s specification in the title (5 HP, ~1925 CFM, upblast design) confirms it’s a commercial-grade rooftop exhaust solution sized for substantial kitchen or facility ventilation loads. Why this is a strong choice - Performance: ~1925 CFM with a 5 HP motor gives robust airflow suited to medium‑to‑large hood systems or high-demand general exhaust applications. - Design and value: The upblast configuration efficiently throws discharge vertically away from the roofline, reducing recirculation and improving dispersion—helpful for commercial kitchens and odor control. At this price from a reputable maker (Captive-Aire), you get commercial reliability without approaching your budget cap. Budget fit Priced at $739.90, this fan is well under your $1,500 budget (roughly $760 of room remaining). That margin lets you allocate funds for professional installation, a roof curb, motor starter or VFD, ducting, and any required controls or permits. Things to consider: - Confirm electrical requirements (voltage, phase, and full‑load amps) and that your site supply matches the fan; a 5 HP motor may need three‑phase or dedicated circuits. - If used for grease‑laden kitchen exhaust, verify the fan is grease‑rated or install proper grease collection and filters upstream. - Plan for roof curb, structural support, vibration isolation, weatherproofing, and backdraft prevention. - Coordinate makeup air, fire/hood interlocks, and local code/permit compliance. - Use a licensed HVAC/electrical contractor for installation and commissioning. This Captive-Aire upblast fan is a solid, cost‑effective commercial choice when paired with the proper electrical, mounting, and grease-control provisions.

FAQ
What should I prioritize when choosing a commercial exhaust fan?
Start by sizing airflow (CFM) to your hood’s capture area and total static pressure, including duct length and filters. Select the discharge style (upblast for grease‑laden kitchen exhaust; downblast or wall for general ventilation). Confirm voltage/phase, motor amperage, and roof curb size. Finally, consider noise, speed control, access for cleaning, and availability of accessories. A quick rule: match CFM and pressure first, then choose discharge style to fit code and layout.
How do I balance cost and value for a rooftop exhaust fan?
Focus on total installed cost: fan price, curb/adapter, electrical work, and commissioning. Paying more for a well‑matched, durable unit often reduces downtime and maintenance. If you’re running a commercial kitchen, prioritize airflow at design static pressure, compatible controls, and service access. Save by avoiding oversizing and optional features you won’t use. Keep a small contingency for curb adapters, weather caps, and speed control if required.
When should I choose upblast over downblast or a wall‑mount fan?
Use upblast when exhausting hot, grease‑laden air from commercial kitchen hoods; it discharges above the roofline and aligns with common code expectations. Downblast can suit non‑grease areas like restrooms or general spaces. Wall‑mount fans are for barns, shops, or ancillary rooms and typically aren’t acceptable for main kitchen hood exhaust. Always verify local code, hood type, and grease filtration before selecting discharge style.
What ongoing maintenance do these systems need?
Set a routine to clean the wheel/impeller, housings, and accessible duct sections, and to check fasteners, vibration, and electrical connections. Inspect any filters or grease collection devices at the hood. Verify that speed controls (if used) operate smoothly and that airflow meets design. Schedule deeper cleanings during off‑hours and document service intervals. Follow manufacturer instructions and safety practices when working at height or around energized equipment.
How do I troubleshoot a noisy rooftop exhaust fan before calling a technician?
Shut power, then check for loose fasteners, debris in the wheel, misaligned curb gaskets, and worn isolation mounts. Spin the wheel by hand to feel for rubbing or bearing roughness. Restore power briefly to confirm the speed controller (if present) isn’t inducing chatter; test at full speed. Persistent vibration, motor overheating, or tripped breakers indicate a service call. Avoid operating with rubbing components to prevent further damage.
