Filtro de poeira Rittal SK 3321.700, branco, 89×89×10 mm, pack de 5

Rittal SK 3321.700 replacement dust filters, supplied as a pack of 5, are compact white filtration panels measuring 89 × 89 × 10 mm. These filters are designed for installation in enclosures, ventilation openings and small air inlets to reduce particulate ingress while allowing continued airflow. Their slim profile suits confined spaces where protection from dust and debris is required without significant obstruction to ventilation.

Advantages

The filters provide consistent particulate retention with minimal airflow restriction thanks to their thin, stable media and frame. Packaged in a set of five, they enable straightforward replacement cycles and spare-parts provisioning for multiple units. The neutral white color simplifies visual inspection for contamination and helps maintain a uniform appearance in control cabinets and ventilation grilles.

Suitable for

• Industrial control cabinets and electrical enclosures
• Small HVAC vents and local ventilation outlets
• Cooling inlets on drives, power supplies and small equipment
• Maintenance spares for workshops and plant environments

Key specifications

• Color: white
• External dimensions: 89 × 89 × 10 mm
• Packaging: pack of 5 filter elements
• Application: compact particulate filtration for ventilation openings
• Mounting: designed for simple insertion into compatible filter frames or grilles

How to use

Measure the ventilation opening or existing filter frame to confirm compatibility with the 89 × 89 × 10 mm dimensions. Remove the old filter element and inspect the housing for accumulated debris; clean the frame if needed before inserting the new filter. Install the filter with the media facing the airflow direction recommended by the enclosure manufacturer, ensuring a secure fit so air passes through the filter surface. Replace filters on a schedule based on dust load and operating conditions or when visual inspection shows significant contamination.

Recommendations

For reliable performance, follow a preventive replacement interval determined by site conditions: inspect filters monthly in heavy-dust environments and every three to six months in cleaner locations. Avoid compressing or folding the filter media during handling, and store spare filters in a dry, dust-free location until installation.
