Updated June 2026 · 12 min read · Singapore's industrial cooling specialist
Singapore's heat and humidity are relentless. For businesses operating warehouses, factories, F&B kitchens, gyms, or event spaces, keeping workers and customers comfortable is not just a welfare issue — it directly affects productivity, safety, and revenue. A warehouse worker operating in 35°C heat makes more mistakes and tires faster. A hawker centre with poor airflow loses customers. A gym without proper ventilation gets negative reviews.
The iFan industrial drum fan range, distributed by PowerPac Singapore, addresses all of this with serious engineering — brushless DC direct-drive motors, 6-blade high-flow systems, heavy-duty swivel wheels for easy repositioning, and airflow figures that standard standing fans simply cannot match. This guide covers all five models, explains exactly which environments each one suits, and gives you the full technical picture to make the right decision for your business.

🏭 Who needs an industrial drum fan in Singapore?
A standard standing fan moves roughly 600–900 m³/hr of air. The smallest iFan drum fan moves 20,000 m³/hr — over 20 times more air. That gap explains why standard fans feel inadequate in larger spaces, and why industrial drum fans exist as a separate category entirely. Here are the Singapore environments where these fans make a measurable difference:
iFan 36" Industrial Drum Fan — IF3622
Model: IF3622 · 36" (90cm)
iFan 36" Industrial Drum Fan — Powerful, Portable, Direct-Drive
Businesses that need a powerful fixed-direction airflow blast — pointed at a specific work area, down a loading bay, or along a production line — will find the IF3622 the most straightforward choice in the range. The 500W brushless DC direct-drive motor generates 20,000 m³/hr of airflow, enough to move air across a distance of 20–30 metres. Variable speed control lets you dial down for ambient ventilation or push to full power during peak heat hours.
Operators in Singapore workshops who have used standard 18" standing fans know the frustration — they cool a small circle around them and nothing else. The IF3622 changes the dynamic entirely: one unit positioned strategically can ventilate an area that would have previously needed six or eight smaller fans.
- 🌀 20,000 m³/hr airflow — ventilates large spaces effectively
- ⚡ 500W brushless DC direct-drive motor — efficient and low-maintenance
- 🎛️ Variable speed control — adjust to conditions
- 🔒 Small grill openings — safety-designed for busy work environments
- 🛞 4" heavy-duty swivel casters — easy repositioning across factory floors
- 🔌 5.6m cable — flexible placement without extension leads
- 🛡️ 24-month motor warranty with proof of purchase
- ⏱️ Rated for 8 hours daily operation for 3 years
iFan 36" Industrial Drum Fan with Oscillation — IF3688
Model: IF3688 · 36" (90cm) with Oscillation
iFan 36" Industrial Drum Fan with Oscillation — Wider Coverage, Same Budget
The IF3688 is the IF3622 with one critical upgrade — oscillation. At exactly the same $899 price, the IF3688 sweeps side to side as it runs, distributing airflow across a wider arc rather than projecting in a single fixed direction. For environments where people are moving around — gyms, event spaces, hawker centres, retail floors, sports halls — this makes a substantial difference. Instead of cooling a corridor directly in front of the fan, it covers the full space from wall to wall.
Singapore event organisers and gym operators consistently favour oscillating drum fans over fixed ones: with a fixed fan, guests or members on either side of the airflow path feel little benefit. With oscillation, the same fan serves the whole room. Given the identical price point, the IF3688 is the default recommendation unless your use case specifically requires a sustained directional blast.
- 🔄 Oscillation — sweeps side to side for wider area coverage
- 🌀 20,000 m³/hr airflow — same power as IF3622
- ⚡ 500W brushless DC direct-drive motor
- 🎛️ Variable speed control
- 🔒 Small grill safety openings
- 🛞 4" heavy-duty swivel casters
- 🔌 5.6m Singapore 3-pin cable
- 🛡️ 24-month motor warranty
iFan 48" Industrial Drum Fan — IF4822
Model: IF4822 · 48" (122cm)
iFan 48" Industrial Drum Fan — The Step Up for Larger Spaces
When a 36" fan is not enough — when the space is larger, the heat load is higher, or the distance the air needs to travel is greater — the IF4822 is the natural next step. The 48" blade system generates significantly more airflow than the 36" models, making it suitable for large commercial environments: sizeable warehouses, supermarkets, large F&B kitchens, covered carparks, sports halls, and industrial facilities where consistent full-space ventilation matters.
Facilities managers at larger Singapore businesses who are used to running multiple smaller fans and still finding the space uncomfortable will typically find one IF4822 does more work than two or three standing fans combined, at a fraction of the energy cost proportionally. The mobile caster system makes repositioning straightforward despite the larger footprint.
- 🌀 30,000+ m³/hr airflow — significantly more than 36" models
- ⚡ 600W brushless DC direct-drive motor — higher power for larger areas
- 📏 48" / 122cm blade diameter — covers larger cross-section in one sweep
- 🛞 Heavy-duty mobile casters — repositionable by one person
- 🔒 Safety grill design — appropriate for busy commercial environments
- 🔌 Singapore-standard 3-pin plug — plug and play, no adaptors
- 🛡️ 24-month motor warranty with proof of purchase
iFan 60" Industrial Drum Fan — IF5922
Model: IF5922 · 60" (152cm)
iFan 60" Industrial Drum Fan — Maximum Airflow for Heavy-Duty Environments
The IF5922 is the flagship of the iFan industrial range — and its status as the best seller with 110 units sold tells you something important: the businesses that need this level of cooling are not hesitating. A 60" drum fan with 50,000+ m³/hr of airflow is a serious piece of industrial equipment. At $2,999 against an original price of $6,999, the $4,000 saving is the largest in the entire PowerPac catalogue.
Shipyards, large manufacturing facilities, aircraft hangars, large-scale event setups, and substantial warehouse operations are the typical buyers. The 60" blade diameter means a single unit covers the cross-section of a large industrial space in a way that smaller fans simply cannot replicate. With only 10 units remaining and no published restocking timeline, buyers who have been considering it should act on the current price rather than wait.
- 🌀 50,000+ m³/hr airflow — maximum industrial-grade cooling
- ⚡ 550W direct-drive motor — built for sustained heavy-duty operation
- 📏 60" / 152cm blade — the largest drum fan in the iFan range
- 🏭 Designed for warehouses, shipyards, hangars, large events
- 🛞 Heavy-duty swivel casters — mobile despite the size
- 🛡️ 24-month motor warranty
- 💰 $4,000 saving against original RRP — largest saving in the range
- ⚠️ Only 10 units remaining at this price
🆕 NEW — iFan 38" Industrial Drum Fan — IF3822
Model: IF3822 · 38" (97cm)
iFan 38" Industrial Drum Fan — The Versatile Mid-Size New Addition
The newest addition to the iFan industrial drum fan range. The IF3822 fills the gap between the 36" and 48" models — a 38" blade system with 550W brushless DC motor that targets versatile mid-size commercial environments. Based on the iFan product lineup, it is specifically recommended for gyms, production areas, warehouses, retail stores and event halls — spaces that need more than the 36" can deliver but don't require the full 48" or 60" scale.
- 🌀 550W brushless DC motor — powerful and energy efficient
- 📏 38" blade diameter — sits between the 36" and 48" in coverage
- 🏋️ Ideal for gyms, production areas, retail, event halls
- 🛞 Heavy-duty swivel casters — fully mobile

❓ Frequently asked questions
How is a drum fan different from a regular standing fan?
A drum fan (also called a barrel fan) is designed to project a column of air directly forwards over a long distance, rather than distributing air in a wide circular pattern like a pedestal fan. A standard 18" standing fan moves roughly 600–900 m³/hr; the iFan IF3622 moves 20,000 m³/hr — about 25 times more air. The result is meaningful ventilation across a large industrial or commercial space, not just a local breeze at one point.
What is the noise level and is it suitable for public-facing environments?
The IF3622 and IF3688 operate at 72.8 dB at maximum speed — comparable to a vacuum cleaner. For warehouse, factory, and construction environments this is entirely acceptable. For public-facing spaces like gyms, event tents, or retail floors, variable speed control lets you run at lower speeds and lower noise levels while still providing meaningful airflow.
Do I need special electrical wiring to run these fans?
No — all iFan drum fans come with a Singapore-standard 3-pin plug and operate on 220V 50/60Hz, which is standard Singapore mains supply. You plug them into any standard 13-amp socket. No rewiring or industrial electrical supply is required.
Are these fans suitable for outdoor use in Singapore's rain?
The iFan drum fans are designed for indoor and sheltered commercial environments. For partially covered outdoor environments such as event tents or void deck setups, they perform well as long as the fan itself is sheltered from direct rain contact. For fully outdoor unprotected environments, consult PowerPac directly to confirm suitability.
What does the 24-month motor warranty cover?
The 24-month motor warranty covers the brushless DC motor against defects in materials and manufacturing faults, with proof of purchase. Warranty service is handled by PowerPac's local Singapore team at +65 6214 9555. Register your product at onlinesvc.powerpac.com.sg.
How many fans do I need for my space?
As a general guide: a single IF3688 (36") effectively ventilates spaces up to approximately 400–500 m². The IF4822 (48") covers up to approximately 700–800 m². The IF5922 (60") is suited to spaces above 1,000 m² or environments with very high heat loads. Contact PowerPac's sales team to discuss your specific layout.
Can I get a bulk order discount for multiple units?
