MCLS Series Low Stand ManCooler

Heavy-duty welded steel construction

Thick-gauge barrels and welded rolled angle rings provide structural rigidity and resistance to vibration. Designed for real industrial environments where equipment gets moved, bumped, and repositioned.

Direct-drive industrial reliability

The propeller mounts directly to the motor shaft, eliminating belts, sheaves, and routine tension adjustments. Fewer moving parts reduce maintenance requirements and improve long-term reliability.

High-efficiency cast aluminum airfoil propellers

Precision-balanced airfoil blades generate high CFM with strong air velocity and extended throw. The non-overloading design protects the motor while delivering smooth, powerful airflow.

OSHA compliant guards

Heavy-duty guards provide worker protection, supporting safe operation in active industrial workspaces.

Continuous duty operation

Designed for extended run times in high-heat production environments. Ideal for facilities where fans operate shift after shift.

Low stand industrial base

A stable, floor-mounted base keeps the unit secure during operation while allowing repositioning as workflow changes.

Integrated lifting eye

Standard lifting eye allows safe crane or hoist placement in large facilities and industrial settings.

TE and Hazardous Location motor options

Available with Totally Enclosed (TE) or Hazardous Location (HL) motors in both single-phase and three-phase configurations to match plant safety requirements.

Durable industrial finish

Polyester powder coat protects against corrosion, plant humidity, and industrial contaminants.

Factory assembled and performance tested

Each MCLS industrial man cooler is fully assembled and tested prior to shipment, reducing installation time and ensuring performance upon arrival.

Important Safety Notice

Hazardous location models are supplied with explosion-proof motors and aluminum blades. The hazardous rating applies to the motor only.

The overall finished fan assembly is not represented as certified for hazardous atmospheres.

Application, installation, and wiring must comply with all applicable local, state, and national electrical codes and must be performed by a qualified electrician.

Hazardous location motors cannot be operated into service factor. As a result, fan performance may be slightly lower than published standard ratings.

These units are not suitable for applications where combustible residue, including paint accumulation, may collect on the motor or blade.

Triangle Engineering does not determine site classification or suitability for hazardous locations. Final responsibility for proper equipment selection rests with the purchaser and specifying authority.
