Compatible Replacement & Equivalent Models
The following models are commonly used as direct or near-direct replacements for the SK3325024. Compatibility should be verified against your enclosure cut-out dimensions and voltage requirements before ordering.
| Part Number | Brand | Airflow | Voltage | Notes |
|---|---|---|---|---|
| SK3325100 | RITTAL | 20 m³/h | 115 V AC | 115 V variant of SK3325024 |
| SK3326024 | RITTAL | 30 m³/h | 230 V AC | Higher airflow upgrade option |
| SK3327024 | RITTAL | 55 m³/h | 230 V AC | High-capacity replacement |
| FFU-150-230 | Generic/OEM | ~20 m³/h | 230 V AC | Same cut-out; verify filter mat compatibility |
| LV8U230 | Stego | ~22 m³/h | 230 V AC | Cross-brand equivalent; confirm dimensions |
Important: Third-party equivalents may differ in connector type, filter mat size, or airflow curve. Always cross-reference the datasheet before substitution in safety-critical enclosures.

- Electrical distribution boards in dusty or humid environments
- Automation enclosures in food & beverage, automotive, and chemical industries
- Outdoor telecom and utility cabinets requiring IP 54 protection
- Server and network enclosures in light industrial settings
System Compatibility
The SK3325024 is compatible with the following RITTAL enclosure families and third-party enclosures with equivalent cut-out dimensions:
- RITTAL TS 8 – Full compatibility; standard snap-in fit
- RITTAL AX – Compatible with appropriate adapter plate
- RITTAL SE / KX – Verify cut-out size (119 × 119 mm required)
- Third-party enclosures – Compatible if cut-out is 119 × 119 mm and panel thickness ≤ 3 mm
- Filter mat compatibility: RITTAL SK 3329.100 (standard), SK 3329.110 (fine filtration)
Selection Guide
Use the following decision framework to confirm the SK3325024 is the right unit for your application, or to identify a more suitable alternative:
- Step 1 – Determine required airflow: Calculate enclosure heat dissipation (W) and required airflow (m³/h). SK3325024 suits enclosures with ≤ 15–20 W heat load at standard ambient temperatures.
- Step 2 – Confirm supply voltage: SK3325024 = 230 V AC. For 115 V AC, select SK3325100. For 24 V DC, consider SK3305230.
- Step 3 – Verify cut-out dimensions: Required panel cut-out is 119 × 119 mm. Measure your enclosure before ordering.
- Step 4 – Assess filtration requirement: Standard G2 filter mat is included. For fine dust environments, upgrade to SK 3329.110 filter mat.
- Step 5 – Check IP rating need: SK3325024 achieves IP 54 with filter mat installed. For IP 55+, consider sealed cooling units.
- Step 6 – Consider airflow upgrade: If heat load exceeds 20 W, evaluate SK3326024 (30 m³/h) or SK3327024 (55 m³/h).

Replacement & Compatibility FAQ
Q: Can I use a third-party fan filter unit to replace the SK3325024?
A: Yes, provided the cut-out dimensions (119 × 119 mm), voltage (230 V AC), and airflow rating match. However, IP 54 certification may not be guaranteed with non-RITTAL filter mats.
Q: What is the replacement filter mat part number?
A: The standard replacement filter mat is RITTAL SK 3329.100. For finer filtration, use SK 3329.110.
Q: Is the SK3325024 compatible with RITTAL AX enclosures?
A: Yes, with an appropriate adapter plate. Contact us or refer to the RITTAL AX accessory catalogue for the correct adapter part number.
Q: How often should the filter mat be replaced?
A: RITTAL recommends inspection every 3–6 months depending on ambient dust levels. Replace when airflow is visibly restricted or pressure drop increases significantly.
Q: Do you supply the SK3325024 with a warranty?
A: Yes. Genuine RITTAL units carry the manufacturer’s standard warranty. Compatible units carry a 12-month Konmask.com warranty. Contact us for details.
Q: Can I order a sample unit before committing to a bulk order?
A: Yes. Single-unit orders are welcome. Contact us for bulk pricing on 5+ units.
