Filter accessory Rittal 3174.000 — replacement filter mat, white, pack of 3

Rittal 3174.000 replacement filter mat is a pack of three white filter pads designed for use in rack and enclosure filter holders. These spare filter mats capture dust and particulates at ventilation and cooling openings, helping to maintain airflow and protect electronic equipment in IT racks, control cabinets and electrical enclosures. The lightweight, pleatable material is intended for easy installation and periodic replacement to support continued cooling performance.

Advantages

The replacement filter mats provide effective particulate capture without significantly restricting airflow when installed correctly. Supplied as a set of three, they allow scheduled maintenance and timely replacement to reduce the risk of dust accumulation on sensitive components. The neutral white colour helps to visually indicate soiling levels, and the mats are compatible with common filter holders used in fans, fan-and-filter units and certain thermoelectric cooling devices.

Suitable for

• Maintenance of roof-mounted fans and fan-and-filter units in server racks
• Protection of control cabinets and electrical enclosures from dust and particulates
• Replacement in ventilation openings of thermoelectric coolers and small cooling modules
• Routine filter change programs in IT and industrial environments

When it may not be suitable

This filter mat is intended for particulate capture and light protection against splashes; it is not designed as a primary barrier against heavy liquid ingress, corrosive chemicals, or flame exposure. For environments with high humidity, corrosive atmospheres, or where ingress protection ratings are required, consider a sealed or rated filter system rather than this general-purpose mat.

Key specifications

• Pack quantity: 3 filter mats
• Colour: white
• Application: ventilation and cooling openings in racks, cabinets and enclosures
• Primary function: capture of dust and airborne particulates

How to use

Install the replacement mat into the designated filter holder or frame of the fan, fan-and-filter unit or ventilation opening following the enclosure manufacturer's instructions. Ensure the mat sits flush and covers the full airflow aperture to prevent bypass. Replace the mat at regular intervals based on dust load and operating conditions; inspect visually for soiling and reduced airflow, and swap in a new mat from the pack when performance is impacted.

What to consider before purchase

• Confirm physical compatibility with your filter holder or fan-and-filter unit dimensions
• Assess environmental conditions (dust level, humidity, chemical exposure) to ensure this mat meets protection needs
• Plan replacement frequency based on operating hours and contamination rate

Usage recommendations

For reliable airflow and equipment protection, store spare mats in a dry place, visually inspect them during routine maintenance, and replace them before significant pressure drop occurs. Use the pack to perform staggered replacements so that a fresh mat is always available when needed.
