SK3201300 (RITTAL)

Full model designation: SK 3201.300, commonly abbreviated as SK3201300 in industry

✅ Basic Specifications

📌 Product Description

Rittal SK3201.300 belongs to the SK series fan-and-filter units. It is used for air exchange and heat dissipation in electrical cabinets, PLC control cabinets and variable frequency cabinets. External air passes through the filter and enters the cabinet to remove heat from electrical components, while blocking dust and maintaining slight positive pressure inside the cabinet to reduce dust ingress.

Airflow direction: blow air from outside into the cabinet

応用: Indoor industrial control cabinets, non-explosion-proof environments

Spare part: Replacement filter mat SK3201.000

⚠️ Selection & 交換ガイドライン

1. Interchangeable Rittal model with identical cut-out: SK3201.230 (24V DC version). Cannot be directly substituted due to different supply voltage.
2. IP54: Dust protected and splash-proof. Not suitable for direct outdoor exposure to rain.
3. Selection check: Total heat generation inside cabinet, pressure difference between inlet and outlet. Avoid airflow short-circuit when multiple units are mounted in parallel.
4. Common faults: Airflow reduction caused by clogged filter mat, abnormal noise from bearing wear, fan stop due to unstable voltage. Periodic filter replacement is critical for maintenance.

Replacement Classification: Class A = Direct mechanical interchange (same cut-out, snap-in mounting); Class B = Similar dimension, minor cut-out/seal modification required; Class C = Economy general type, for non-critical cabinets in projects

Matching Exhaust Filter (corresponds to Rittal SK3201.200 fanless outlet grille)

Replacement Verification Checklist (Engineering Mandatory)

1. Mounting Interchangeability: Class A units share identical 177×177 cabinet cut-out. Snap-in design enables direct replacement of original SK3201.300 without sheet metal modification. For Class C generic units, verify cut-out tolerance by physical measurement.
2. Bearing Selection: Ball bearing version preferred. Sleeve bearing has short service life and tends to generate noise under high temperature; not suitable for 24/7 連続運転.
3. IP54 Prerequisite: Complete foam sealing gasket must be fitted. IP rating will degrade to IP43 without gasket.
4. Filter Mat Compatibility: Filter mats of Class A brands are interchangeable with Rittal SK3201.000 filter, convenient for spare parts management.
5. Flame Retardancy & 証明書: Check CE & RoHS for export projects; verify 3C certification for domestic projects. Class C low-cost products often lack valid certificates.
6. Airflow Derating: Domestic products quote free-blow airflow. Actual airflow will drop under internal cabinet duct resistance. Reserve margin in thermal calculation.

Selection Recommendation Summary

Projects requiring direct replacement, long-term reliability and spare part compatibility: Leizig FK2202.230 / KAKU FK204230

Bulk panel building projects, コスト優先, standard indoor conditions: Kuangshun ZL804.230

Low budget, short-term retrofit: FB204.230 (inspect bearing and gasket during acceptance)

Risk Warning

Domestic units with identical outer dimension may have minor differences in thickness, gasket protrusion and snap travel. It is recommended to test fit one sample before mass replacement to confirm sealing, snap lock and wiring clearance.

製品の特徴

1. Intake fan: External air passes filter mat and blows into cabinet to remove internal heat. Separate SK3201.200 outlet filter required for exhaust to form convection.
2. IP54保護: Dust protected and splash-proof, suitable for general industrial workshop environment.
3. Tool-free snap-fit housing. Easy filter replacement and fan maintenance.
4. Compatible with Rittal TS, AE, TP standard enclosures; also applicable for retrofitting other brands of electrical cabinets.
5. Ball bearing design for long continuous runtime and low noise.

スペアパーツ & 関連機種

Replacement filter mat: SK3201.000 (consumable item, replace periodically in dusty environment)

115V version: SK3201.310

Matching exhaust filter (ファンレス, only exhaust filtration): SK3201.200

代表的な用途

PLC control cabinet, VFD cabinet, machine tool electrical box, low voltage switchgear, automation line control cabinet, indoor non-explosion-proof service

選択 & トラブルシューティング

1. Thermal airflow sizing: Total power dissipation, temperature difference between cabinet inside/outside and duct resistance reduce actual airflow. Do not use nominal 105 m³/h directly for thermal calculation.
2. Installation suggestion: Mount intake fan at lower section of cabinet; fit exhaust filter at upper section. Take advantage of hot air rising to improve cooling efficiency.
3. Common faults: Reduced airflow → clogged filter mat; fan fails to start → check AC230V supply; abnormal noise → bearing degradation.
4. Replacement strategy: Domestic 204-type fan-and-filter units can be mechanically interchanged, but IP rating, fan service life and flame retardancy must be rechecked.

Leizig FK2202.230｜Installation Instruction (Replacement for Rittal SK3201.300, Snap-in Embedded)

取付タイプ: Embedded snap-in mounting on cabinet sheet metal panel (main housing fixed without screws). Can be fitted on cabinet side panel, door or top plate; Airflow Direction: Outside air → filter mat → fan → blow into cabinet (intake type)

1. Sheet Metal Cut-out Requirement (Fully compatible with Rittal SK3201.300, no cut-out modification for direct replacement)

Panel cut-out: 177 × 177 mm square

Outer frame dimension: 204 × 204 mm, overall depth 104 mm

Applicable sheet metal thickness: 1.5mm～2.5mm standard Rittal cabinet sheet metal (too thick: snap cannot lock; too thin: sheet metal prone to deformation)

Deburr cut edge to prevent gasket damage

2. Step-by-step Installation
3. Power Isolation Precondition

Disconnect cabinet power supply; confirm no live working. Clean burrs and grease around cut-out.

2. 設置前検査

Verify the foam rubber gasket on rear side of unit is intact and undamaged (critical for IP54 protection). Confirm four spring clips are fully open.

3. Push-in from Cabinet Exterior (Standard Method) ✅

Align FK2202.230 with the 177×177 cut-out from outside of cabinet, press evenly on four corners of panel. Fourclick sounds indicate four spring clips snap and lock onto inner side of sheet metal.

Panel sits flush against cabinet outer surface; gasket is compressed to achieve dust and splash sealing.

4. Cabinet Internal Wiring (AC220/230V)

Fan comes with terminal block (L live / N neutral / PE earth). Terminate wiring inside cabinet. Miniature circuit breaker is recommended for protection. PE ground wire must be reliably earthed.

5. Filter Cover Removal for Maintenance

Front louver grille is snap-fit. Pull outwards without tools to remove foam filter mat; clip back after replacement.

6. Removal Procedure

Pinch four spring clips inward from cabinet interior, push unit outward simultaneously to extract fan.

オプション: For rare cases with thin sheet metal or heavy vibration, four M4 self-tapping screws can be added into pre-drilled holes on panel corners for reinforcement (not required by original design; snap fixation is sufficient).

3. 取付方向 & Airflow Design Guidelines (Engineering Focus)

FK2202.230 is an intake fan: install at the lower section of cabinet to draw in cool ambient air;

Fit Leizig FK2202-OUT (fanless exhaust filter) at upper cabinet to establish natural thermal convection;

Do NOT invert or mount at top for exhaust. Exhaust operation will burn filter mat and invalidate IP protection.

4. Installation Acceptance Criteria
5. No obvious gap around panel; gasket compressed uniformly.
6. All four clips fully engaged; no wobble when manually shaking unit.
7. Power-on test: Air blows from outside into cabinet.
8. No blade rubbing or abnormal noise.
9. Minor Installation Differences vs Rittal SK3201.300

✅ Same cut-out and snap mechanism, direct replacement without sheet metal modification

⚠️ Two minor differences:

1. Slightly different spring clip tension; higher pressing force required for 2.5mm thick cabinet sheet metal.
2. Slight variation in gasket cross-section dimension. Sample test fit is required to verify sealing performance.
