## Summary description

Rittal 3321.705 is a replacement filter membrane designed for enclosure and cabinet ventilation systems. It serves as filter media to prevent dust ingress and protect internal components in electrical and electronic enclosures. Suitable for use as a maintenance spare in industrial cabinets, server racks and control panels where reliable particulate filtration is required.

## Long description

The Rittal 3321.705 filter membrane is a chopped-fibre mat designed for enclosure ventilation and air filtration in electronic and electrical cabinets. It features a progressive structure with an open side for dust-laden air and a closed side for clean air, offering reliable filtering of most dust particles from around 10 µm. The material is temperature-resistant up to 100°C and meets self-extinguishing category F1 according to DIN 53 438.
Advantages
The progressive chopped-fibre construction provides effective capture of particles while maintaining airflow. The dual-sided design—with an open structure facing the dust-laden air and a closed structure on the clean-air side—helps prolong service life and simplifies installation orientation. Temperature resistance to 100°C and F1 self-extinguishing classification increase safety in electrical enclosures.
Suitable for
Ventilation and filtration panels in electrical and electronic enclosures
Replacement filters for Rittal SK series and similar cabinet filter housings
Applications requiring removal of dust from approximately 10 µm and larger particles
When it may not be suitable
This filter membrane is not intended for capturing submicron particles or for HEPA-level filtration; it is designed for coarse to medium dust filtration starting at about 10 µm. It may not be appropriate where oil mist, sticky contaminants, or chemical vapours are present without additional specialized filtration.
Key specifications
Material: chopped-fibre mat with progressive structure
Particle retention: effective from approximately 10 µm
Temperature resistance: up to 100°C
Fire behaviour: self-extinguishing category F1 (DIN 53 438)
Structure: open side for dust-laden air, closed side for clean air
How to use
Install the filter membrane in the filter frame or housing with the open-structure side facing the incoming, dust-laden airflow and the closed-structure side facing the enclosure interior. Replace the membrane according to the equipment manufacturer’s maintenance intervals or whenever pressure drop increases noticeably. Ensure correct seating and sealing to prevent bypassing of unfiltered air.
What to consider before purchase
Confirm compatibility with the filter frame or holder dimensions and the specific Rittal SK model if replacing original parts
Assess required particle retention: this membrane is intended for coarse/medium dust from ≈10 µm, not for HEPA-level filtration
Consider environmental factors such as oil, chemical vapours, or moisture that may require specialised media
Usage recommendations
For correct performance, orient the membrane with the open side toward incoming air, perform regular inspections for clogging, and replace when airflow is substantially reduced or after recommended service intervals.
