Rack accessory filter Rittal 3171.120 — white replacement filter, pack of 5

Rittal 3171.120 is a white replacement pleated filter supplied as a pack of 5, designed for use as a rack accessory in ventilation and filtration applications. The pleated filter design increases volumetric air flow compared to conventional chopped-fibre mats, improving cooling performance while reducing energy consumption. It is intended for maintenance and service of enclosures and filter fans where controlling dust and particulate ingress is required to protect electronic components and extend maintenance intervals.

Advantages

The pleated construction delivers higher airflow capacity and lower pressure drop, which supports more efficient cooling and reduced energy use for fan units. Improved filtration properties trap more dust and particulates, helping to keep enclosure interiors cleaner and lengthening maintenance cycles. Supplied as a pack of five replacement filters, the product simplifies scheduled maintenance and spare parts management.

Suitable for

• Replacement filtration in compatible filter fans and outlet filters for server racks and control cabinets
• Maintenance of electrical or electronic enclosures where dust control is required
• Industrial and data centre environments with standard ventilation systems

When it may not be suitable

This replacement filter is designed for use with compatible Rittal or similarly sized filter fan and outlet filter housings; it may not fit non-compatible or custom-sized ventilation assemblies. It is intended for particulate filtration and is not a substitute for gas, chemical or HEPA filtration where specialized air quality requirements are present.

Key specifications

• Colour: white
• Construction: pleated filter media
• Pack quantity: 5 replacement filters
• Function: particulate/dust filtration for rack/filter fan applications
• Effect on airflow: higher volumetric airflow and lower pressure drop compared with chopped-fibre mats

How to use

Turn off power to the fan or enclosure before performing maintenance. Remove the old filter from the filter fan or outlet filter housing and inspect the housing for debris or damage. Install the Rittal 3171.120 replacement filter ensuring correct orientation and full seating in the filter frame or housing. Restore power and verify normal fan operation and airflow. Replace filters at regular intervals depending on ambient contamination levels and operational guidelines.

What to consider before purchase

• Confirm physical compatibility with your filter fan or outlet filter housing and mounting dimensions
• Assess the required filtration level — this product is for particulate/dust control, not for gas or HEPA-grade filtration
• Estimate replacement frequency based on ambient dust levels and operational hours to determine pack quantity needs

Usage recommendations

For reliable performance, follow the enclosure manufacturer's maintenance schedule, inspect filters visually at regular intervals, and replace filters sooner in dusty or industrial environments. Properly fitted pleated filters help maintain cooling efficiency and reduce overall service costs.
