HOFFMAN ENCLOSURES TEP4 Fan Filter With Exhaust Grille
This enclosure cooling option combines a fan filter with an exhaust grille, designed for Hoffman cooling and exhaust fans. It fits a 160 x 187 mm fan size with 162 mm fixing centers and uses a stainless steel guard with an aluminium filter. Best for industrial enclosures where durable protection and effective filtration matter. Choose this if your system needs a robust guard and a metal filter for long-term maintenance. A potential limitation is that the data focuses on unit-level specs; verify compatibility with your exact Hoffman model before ordering.
696N-R02 B Unit Replacement Grille Kit
This replacement grille kit includes the 696N-R02 B Unit and 97011723 grille cover. It’s designed for multiple Broan-NuTone and Nutone fans and housings, including 663, 670, 671, 688, and 689 series, with 7.5″ x 7.25″ housings. Best for homeowners and contractors maintaining older or mixed-brand bathroom exhaust systems. Better for projects requiring cross-brand compatibility. A limitation is that the exact model fit depends on your current fan motor and housing, so confirm the matching numbers before purchase.
Schneider Electric ClimaSys CV Axial Motor Cooling Fan
This axial cooling fan for electrical boxes delivers up to 80 m3/h at 50 Hz with a standard filter. It’s designed for easy installation, using a 125 x 125 mm cut-out and straightforward wiring. The durable ASA PC grey grille and IP54 protection make it well-suited for humid or dusty environments. Best for compact enclosures needing reliable cooling and a durable exterior. Choose this if you value a proven Schneider Electric solution with protected airflow paths. A potential drawback is that the specified airflow rate may be insufficient for very large enclosures or high-heat loads.
Hoffman / nVent Exhaust Grille Kit for Filter Fan
This non-metallic exhaust grille kit is sized for Hoffman HF04 series side-mount cooling fans. It’s gray and IP54 rated, with external dimensions around 112.27 x 112.78 x 51.31 mm. Best for a compact, lightweight enclosure setup where a plastic grille is preferred for corrosion resistance. Choose this if you’re using Hoffman HF04 cooling fans; avoid if your enclosure requires metal guards or higher mechanical durability in harsh environments.
Broan-NuTone FG701S Universal CleanCover
This universal CleanCover grille is a white, low-profile option compatible with various housing dimensions. It’s a genuine Broan-NuTone part, designed for easy installation with springs included. Best for bathroom fans where a clean, minimal ceiling footprint matters. Choose this if you want a straightforward, manufacturer-backed replacement for a variety of Broan-NuTone housings. A limitation is that exact fit varies by housing size; verify compatibility with your fan’s model before purchasing.
Broan 682 Bathroom Ventilation Fan With Charcoal Filter
This versatile fan model helps remove humidity, smoke, and cooking odors with a replaceable activated charcoal filter. It supports efficient air circulation in compact spaces and can be mounted between ceiling joists or wall studs. Best for bathrooms and small utility rooms where odor control is a priority. Consider this option if you need an easy, compact installation; note that performance depends on proper filter maintenance and seating in a standard 2 x 4 inch space.
MAYITOP Grille Assembly Replacement for Broan Nutone
This grille assembly is designed as a direct replacement for specific Broan Nutone models, including 682NT, 682, and the older 681 with 7-1/8″ x 7-1/8″ housings. Best for replacing worn or incompatible grilles without swapping the entire fan. Choose this if you’re maintaining older Broan/Nutone systems; it helps restore proper airflow and appearance. A caution is that it targets specific housing measurements; confirm your dimensions before purchasing.
Buying Guide
What should you verify before buying enclosure fans and exhaust grilles?
- Airflow needs: measure enclosure volume and desired air changes per hour to pick a unit with appropriate m3/h rating.
- Mounting compatibility: confirm cut-out sizes and fixing centers match your enclosure or housing.
- Protection rating: IP54 or higher is preferable in humid or dusty environments.
- Materials: metal guards are durable in industrial settings; plastic guards resist corrosion in damp areas.
- Replacement parts availability: choosing brands with widely available grilles and filters reduces maintenance downtime.
- Ease of installation: consider models with simple snap-in or spring-based mounts for faster setups.
How to choose by environment
Industrial enclosures benefit from robust guards and filters for dust and moisture. Bathrooms demand moisture-resistant materials and easy, quick installation. For mixed-brand systems, replacement grille kits should offer broad compatibility. If noise is a concern, review the unit’s decibel rating, especially in quiet office zones or residential settings.
Common questions
- What is the typical airflow rating for enclosure fans? Airflow varies; select a model that matches your enclosure size and heat load.
- Are IP ratings important? Yes, IP54 or higher protects against dust and splashes in many installations.
- Can I replace just the grille? Often yes, when a compatible grille kit exists for your fan model.
- Do I need a filter with every fan? Not always, but filters improve air quality and protect internal components in dusty environments.
The selections above balance compatibility, durability, and ease of installation across a range of enclosure types. When in doubt, verify exact model numbers and housing dimensions with the manufacturer’s documentation before purchasing.
