PC3021 Portable Cooler Mini

Compact 30 inch barrel Industrial-grade airflow in a footprint that fits a two-car garage bay, a shop aisle, or a patio corner. At 33 inches wide and 34 inches tall, it goes through standard doorways without disassembly.

Two-speed direct drive motor No belts, no pulleys, no tensioning, no alignment. Direct drive means the blade mounts straight to the motor shaft, which removes the single most common maintenance item on a portable fan.

8,200 CFM on high, 6,600 CFM on low High speed for knocking down heat fast in an open bay. Low speed for steady background air movement when you want circulation without the noise and wind.

Deep-pitch blades More aggressive blade pitch moves more air per revolution, which is how a 1/4 HP motor delivers airflow numbers this strong at this diameter.

Heavy-gauge painted steel barrel Not spun plastic. The steel barrel takes shop abuse, resists dents from forklifts and ladders, and keeps the blade shrouded and protected.

Caddy cart handle Tilt it back like a hand truck and roll. Two wheels and a 55 pound total weight mean one person repositions it in seconds without lifting.

OSHA-compliant spiral-wound wire guards Front and rear guard spacing meets OSHA requirements, which matters for insurance inspections and any commercial or job-site environment.

Ships assembled and tested Attach the handle and plug it in. No blade balancing, no motor wiring, no bracket assembly.

Model: PC3021

Power requirements: The PC3021 draws 3.5 amps at 115V, so it runs on any standard household or shop circuit. Multiple units can typically share a single 15 amp circuit, though you should confirm total connected load against your breaker and account for motor inrush at startup.

Workshops and home garages The most common use for a 30 inch barrel fan. One unit moves enough air to keep a two-car garage or home shop comfortable through summer without the cost or install work of a mini split.

Small shops and workstations Spot cooling for a welding bay, a bench, a paint prep area, or a machine station. Aim it where the person is instead of trying to condition the whole building.

Automotive and repair shops Rolls between bays as work moves. The steel barrel handles the environment, and the direct drive motor is not affected by the dust that eats belt-driven equipment.

Woodworking shops Keeps air moving over the bench and helps clear finish fumes and airborne dust when paired with proper dust collection and ventilation.

Patios, decks, and outdoor events Light enough to move for a weekend and put away Monday. Good for covered patios, tents, tailgates, receptions, and outdoor dining setups.

Job sites Rolls off a truck, plugs into a standard outlet or generator, and moves air for crews working in enclosed or partially framed spaces.

Water damage restoration and drying Strong directed airflow accelerates evaporation on wet floors, framing, and drywall. The rolling caddy design makes it easy to reposition as the drying pattern changes.

Barns, stables, and kennels Air movement is the cheapest livestock heat-stress mitigation there is. The compact size fits aisles and stall fronts where a 48 inch drum fan will not.

Greenhouses and grow spaces Keeps air circulating to reduce hot pockets and stagnant humidity around canopy level.

Home gyms and finished basements High airflow with a two-speed switch, so you can run it low for steady circulation without the wind tunnel effect.

Triangle Engineering has been building industrial ventilation in Jacksonville, Arkansas since 1948. Portable Cooler Mini’s are built in the USA with a blend of domestic and foreign components, assembled and performance-tested at our own factory before they ship.

That matters for a practical reason more than a patriotic one. When a fan is built here, parts stay available here. Motors, blades, switches, and wheels are stocked and ship from Arkansas, and you talk to a person who knows the product when you call. Imported fans built to a price point are supported until the container sells out and then they are orphaned.

The Portable Cooler Mini is fully supported with stocked replacement parts: motors, blades, switches, and wheels. Maintenance is fast, downtime stays short, and a fan that has run for a decade can be put back into service for the cost of a part instead of the cost of a new unit.

Low-cost imports flood this market with fans designed to be replaced rather than repaired. When the motor fails at year three, there is no part number to call about. Every Triangle fan is built to be serviced, which is why our fans stay in operation for years instead of ending up in a landfill.

Choose the PC Mini (30″) if: you are cooling a home garage, a single workstation, a patio, or any space where a full-size drum fan is too large or too heavy to reposition easily.

Choose the PC Series HD (larger diameters) if: you need to move air across a full warehouse bay, a production floor, or a large open shop, or you need higher CFM per unit than the Mini delivers.

Consider a mounted fan instead if: the fan will live in one place permanently. Wall and ceiling mounted models free up floor space and remove the trip hazard of a cord across a work area.

Triangle Engineering builds portable barrel fans in belt drive and direct drive, floor standing and mounted, across a full range of diameters and horsepower.

How much air does a 30 inch barrel fan move? The PC3021 moves 8,200 CFM on high and 6,600 CFM on low. For reference, that is enough to turn over the air in a standard two-car garage several times per minute, though barrel fans are generally used for directed spot cooling rather than whole-room air exchange.

What is the difference between a barrel fan and a drum fan? Nothing. The two terms describe the same product: a fan with its blade housed inside a cylindrical steel barrel. “Drum fan” is more common in the rental and retail channels, “barrel fan” in industrial supply.

Is direct drive better than belt drive? For a fan this size, yes, for most buyers. Direct drive removes the belt and pulleys, which are the parts that need periodic tensioning and eventual replacement. Belt drive earns its place on larger fans where it allows the motor speed and blade speed to be tuned independently.

What outlet does the PC3021 need? A standard 115V single-phase outlet. The fan draws 3.5 amps and comes with a 10 foot cord and molded plug, so no electrical work is required.

Can I use it outdoors? Yes, on covered patios, under tents, and on job sites. Like any electric fan, it should not be left out in rain or standing water, and outdoor use should be on a properly grounded circuit.

Is it good for drying after water damage? Yes. High-volume directed airflow speeds evaporation from floors, framing, and drywall, and the rolling caddy makes repositioning easy as drying progresses.

Does it ship assembled? Effectively, yes. Attach the caddy cart handle, roll it into place, and plug it in. Every unit is performance-tested at the factory before shipping.

Can I get replacement parts? Yes. Motors, blades, switches, and wheels are stocked. This fan is built to be serviced, not replaced.

Triangle Engineering has specialized in industrial ventilation since 1948. Our fans are factory-assembled, performance-tested, and backed by stocked replacement parts and a customer service team that knows the products.
