Pak fans price varies widely by capacity, enclosure, motor size, and whether the unit is for rooftop commercial HVAC or process ventilation. Buyers typically pay from a few hundred dollars for small rooftop units to several thousand for industrial packaged fans; major cost drivers are fan size (cfm), motor horsepower, materials, and installation complexity.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small Packaged Exhaust Fan | $350 | $750 | $1,500 | Assumptions: 500–1,200 CFM, 1/4–1 HP, basic galvanized housing. |
| Medium Rooftop Pak Fan | $900 | $2,500 | $5,000 | Assumptions: 1,500–5,000 CFM, 1–3 HP, weatherproof housing. |
| Large Industrial Packaged Fan | $3,000 | $8,500 | $20,000+ | Assumptions: 10,000+ CFM, 5–25 HP, specialty materials. |
| Installation (typical) | $300 | $1,200 | $5,000 | Includes mounting, duct tie-in, wiring; complex rooftops cost more. |
Typical Pak Fans Price for Commercial and Industrial Units
Most buyers should expect total prices grouped by capacity: small 500–1,200 CFM, medium 1,500–5,000 CFM, and large 10,000+ CFM.
Small packaged fans: $350-$1,500 per unit for basic galvanized housings and 0.25–1 HP motors, suitable for small bathrooms, kitchens, or spot exhaust. Average: $750.
Medium rooftop pak fans: $900-$5,000, common for restaurants, retail, and light manufacturing. Assumes 1–3 HP motors, basic weatherproofing, and single intake.
Large industrial pak fans: $3,000-$20,000+, for 10,000+ CFM, multi-stage impellers, 5–25 HP motors, and stainless or coated housings for corrosive environments. Average: $8,500.
Breakdown of Price Components: Materials, Labor, Equipment, and Delivery
A typical quote mixes unit cost with labor, equipment rental, delivery, and disposal; each can be a large share of the final price.
| Component | Low | Average | High | Typical Role |
|---|---|---|---|---|
| Materials | $250 | $1,800 | $12,000 | Fan, housing, motor, mounts |
| Labor | $300 | $1,200 | $4,000 | Mounting, duct tie-in, electrical |
| Equipment | $0 | $150 | $1,200 | Cranes, lifts, scaffolding |
| Delivery/Disposal | $50 | $200 | $1,000 | Freight, old-unit disposal |
| Permits | $0 | $120 | $600 | Local mechanical/electrical permits |
How Capacity, Motor HP, and Housing Material Change the Final Quote
Fan capacity (CFM), motor horsepower (HP), and housing material produce step-changes in price rather than linear increases.
Capacity thresholds: under 2,000 CFM usually fits small/medium units ($350-$2,500); 2,000–10,000 CFM moves to industrial grade ($2,500-$8,500); above 10,000+ CFM often exceeds $8,000. Motor HP jumps: 1 HP vs 5 HP typically raises unit cost by 40%-150% depending on efficiency and controls.
Material thresholds: galvanized vs aluminum adds 10%-30%; stainless or corrosion-resistant coatings add 30%-100% depending on grade.
Cost-Saving Choices When Buying Pak Fans
Simple scope and material decisions can cut the total price substantially without sacrificing function.
- Choose galvanized housing if environment allows instead of 304/316 stainless to save 30%-70% on materials.
- Match motor efficiency to runtime: premium-efficiency motors cost more up front but may reduce lifecycle energy expense; consider lower-efficiency if runtime is under 2,000 hours/year.
- Schedule installation off-season to avoid rush premiums and crane demand that add $500-$2,000.
- Remove old unit yourself to avoid disposal fees of $75-$300.
Regional Price Differences Across U.S. Markets
Labor and freight produce predictable regional deltas: West Coast and Northeast are typically 10%-25% higher than Midwest and South.
Example deltas: Midwest baseline; Northeast +10%-20% on labor and permits; West Coast +15%-25% due to freight and high labor; Rural areas may be baseline or slightly lower but add travel fees of $150-$600.
Typical Installation Time, Crew Size, and Labor Rates
Installation time and crew affect labor line items; expect 1-3 technicians and 2-12 hours depending on complexity.
Small unit swap: 1-2 techs, 1-4 hours, $75-$125 per hour. Medium rooftop install: 2 techs, 4-10 hours, includes crane/lift time. Large industrial install: crew of 3-6, 8-40 hours.
Common Add-Ons, Warranties, and Replacement Parts That Raise the Price
Add-ons such as VFDs, inlet/outlet silencing, and premium coatings can add $300-$6,000 to the base unit cost.
- Variable frequency drives (VFD): $400-$3,000 depending on HP and features.
- Sound attenuators: $200-$2,000 based on length and decibel reduction.
- Extended warranty or service contracts: $100-$800 annually or $200-$2,000 one-time for multi-year coverage.
- Replacement belts, pulleys, or bearings: $25-$400 per part; labor extra.
