OVERVIEW

Looking for a Smarter Way to Cool Large Spaces? This 50 Inch Portable Evaporative Cooler Circulates High-Volume Airflow to Transform Daily Comfort

Heat has a way of settling into big buildings and staying there. Warehouses, factory floors, and repair shops can trap warm air under high ceilings, especially during the summer months. The M-502 portable evaporative cooler from Bud’s Equipment is designed for exactly these environments—places where traditional air conditioning is expensive, impractical, or simply not enough.

This isn’t a small unit trying to cool a massive space. The M-502 is a high-capacity portable evaporative cooler built to move serious air. With its large 50-inch fan and steady operating speed, it creates a wide, consistent stream of cooled airflow that reaches far beyond the area directly in front of it. Instead of cooling a single person or station, it helps create a broad comfort zone across work areas, production lines, and open bays.

The size of the fan matters more than most people realize. A 50-inch blade can push a much higher volume of air than smaller units, which is exactly what’s needed in large, open buildings. The airflow spreads across long distances and covers multiple work zones at once. In many cases, a single portable evaporative cooler of this size can support areas up to 6,200 square feet, making it a practical solution for facilities that need real coverage without installing permanent systems.

Running at around 640 rpm, the M-502 strikes a strong balance between performance and comfort. It moves cooled air far across the floor—while keeping noise and vibration at a manageable level. Workers feel steady airflow rather than a harsh blast, which makes a noticeable difference during long shifts.

There’s also a clear efficiency advantage. An evaporative cooler uses a fan, water, and cooling media rather than a compressor, which means it typically consumes far less electricity than traditional AC systems in large, open spaces. For warehouses, factories, and workshops running daily operations, that lower energy demand can make a meaningful difference over time.

Flexibility is another reason facilities rely on this type of cooling. Heat doesn’t stay in one place. One week the warmest area might be near shipping, the next it’s over by welding, machinery, or a busy production line. Because the M-502 is portable, teams can move it where relief is needed most and adjust as workloads shift.

At its core, this portable evaporative cooler is about creating a more comfortable, workable environment in spaces that are tough to cool. It helps reduce heat stress, supports productivity, and keeps air moving where people need it. In large buildings where airflow makes all the difference, the M-502 delivers steady, wide-reaching cooling without the complexity of permanent systems.

SPECIFICATIONS

FEATURES

• Cools Large Areas Up to 6,200 Sq. Ft.
  Designed for warehouses, factories, and large workshops, the 50-inch fan moves a high volume of air to create a wide cooling zone instead of just cooling one spot. Ideal for open spaces where traditional AC struggles to keep up.
  
  
• Stepless Speed Inverter for Precise Airflow Control
  Built with a direct-drive fan and variable speed inverter, the unit lets you fine-tune airflow to match changing conditions. Increase air movement during peak heat or dial it back for steady, consistent comfort.
  
  
• Energy-Efficient Cooling Without a Compressor
  This portable evaporative cooler lowers temperatures using water instead of refrigerants, which means significantly lower power use. Just add water and let the system do the work—no complex installation or high energy demand.
  
  
• Enhanced Cooling with Ice Port Option
  For extra relief during extreme heat, simply add ice to the built-in port. This boosts the cooling effect and helps drop the felt temperature even more in high-load environments.
  
  
• Low Maintenance, Long-Lasting Components
  Routine care is simple: drain the water tank a couple of times per week and keep operations running. The internal filters are built to last approximately 3–5 years, reducing ongoing maintenance costs.
  
  
• Filters Dust While Delivering Clean, Cool Air
  As it cools, the system also helps clean the air by filtering dust particles. The evaporative process produces no mist, just steady, comfortable airflow that improves air quality and working conditions.
