What These Products Are For

Restoring Safe, Guarded Fan Configurations

Fan guards are used during fan service, replacement work, and routine cleaning to restore protective guarding on commercial fan equipment. Facility and maintenance teams rely on them to replace worn, damaged, or missing guards without replacing the entire fan unit.

How To Choose

Match Guard Type to Your Fan's Size and Service Need

Start with fan diameter and configuration. Choose a standalone guard when only the guard is damaged, or select a guard-and-blade assembly when servicing both together. Hinged designs simplify cleaning access. Confirm finish, blade count, and attachment style match your existing setup before ordering.

Common Applications

Where Fan Guards Are Typically Used

Common applications include facility maintenance shops, warehouses, manufacturing floors, and commercial HVAC service. Guards are frequently replaced during scheduled cleaning cycles, after physical damage, or when upgrading a fan's safety configuration as part of a broader equipment service project.

Additional Information

Construction and Finish Details Worth Knowing

Available finishes include yellow, silver, gray, nickel chrome-plated, and stainless steel. Construction details such as static balancing, positive-locking loops, and four through-bolt motor attachment help ensure a secure, stable fit that matches the original fan configuration.

16" – 30"Fan Diameter Range Covered

This category includes guards and assemblies sized for fan diameters from 16 inches up to 30 inches across multiple commercial fan configurations.

5 Finish OptionsAvailable Guard Finishes

Guards are available in yellow, silver, gray, nickel chrome-plated, and stainless steel to match existing equipment or meet environmental requirements.

Hinged DesignsMaintenance-Friendly Access

Hinged guard configurations allow the guard to open for cleaning and inspection without requiring full disassembly of the fan unit.

3-Blade SteelBlade Assembly Option

Select guard-and-blade sets include three-blade steel assemblies with static balancing for smooth, stable operation after installation.

Planning Guide

Plan the right fit before choosing

Planning Guide

Step 1: Confirm Fan Diameter and Configuration

Fan guard compatibility is determined first by fan diameter. This category covers 16-inch direct-drive low-pressure fans, 18- and 20-inch fan applications, and 20-, 24-, and 30-inch safety fan assemblies. Measure the existing guard or fan blade sweep before selecting a replacement to avoid fitment issues.

  • 16-inch guards are sized for direct-drive low-pressure fan models
  • 18- and 20-inch options cover mid-range commercial fan applications
  • 20-, 24-, and 30-inch guards are available for larger safety fan assemblies
  • Always verify diameter against the fan's existing guard or equipment documentation
Planning Guide

Step 2: Decide Between a Standalone Guard or a Guard-and-Blade Set

If only the guard housing is damaged, a standalone guard is the most cost-effective choice. If the blades are also worn, bent, or missing, a combined guard-and-blade assembly lets you service both components in a single order. Hinged guard designs are worth selecting when frequent cleaning access is a priority.

  • Standalone guards work when blades are still in serviceable condition
  • Guard-and-blade sets reduce labor by combining both replacements into one assembly
  • Hinged designs allow the guard to open without full disassembly for cleaning
  • Three-blade steel assemblies with static balancing are available for select configurations
Planning Guide

Step 3: Match Finish and Attachment Details to the Existing Fan

Finish selection affects both appearance and corrosion resistance. Stainless steel and nickel chrome-plated options offer greater durability in humid or washdown environments. Confirm attachment style—particularly four through-bolt motor attachment—matches the fan's motor mounting pattern to ensure a secure installation.

  • Stainless steel and chrome-plated finishes suit humid or high-wash environments
  • Yellow, silver, and gray finishes are common for standard facility applications
  • Positive-locking loops help secure the guard during operation
  • Four through-bolt attachment must align with the existing motor mounting pattern
FAQ

Common questions before buying

How do I know which fan guard size I need?

Start by measuring the diameter of your existing guard or the fan blade sweep. This category covers 16-inch, 18-inch, 20-inch, 24-inch, and 30-inch configurations. Cross-reference that measurement with your fan's model documentation to confirm the correct fit before ordering.

Should I order a standalone guard or a guard-and-blade assembly?

If your blades are still in good condition, a standalone guard is the more economical choice. If the blades are bent, worn, or missing, a combined guard-and-blade assembly lets you replace both components together and reduces the chance of a second service call.

What is the advantage of a hinged fan guard?

Hinged guards open without requiring full disassembly of the fan, which makes routine cleaning and inspection significantly faster. They are a practical choice for fans that are serviced frequently or installed in locations where access is limited.

Which finish should I choose for a wet or humid environment?

Stainless steel and nickel chrome-plated finishes offer the best corrosion resistance for humid, washdown, or moisture-prone environments. Standard painted finishes in yellow, silver, or gray are better suited for dry indoor facility applications.
