Custom 30,000 m³/h filter unit for fatty acid plant in Indonesia: solution for high dust conditions
2026-07-15
In January 2026, TC Filter Group engineers completed production and shipment of a custom filter unit for a fatty acid production site in Indonesia. The facility is located in close proximity to mining operations, which causes a critically high level of dust in the atmospheric air (cement dust, suspended particles). The customer's specification required not only high cleaning efficiency for industrial and office premises, but also strict adherence to non-standard connection dimensions.
Project Challenge: Custom Flange Geometry
The key difficulty was the unique configuration of the installation space. The inlet and outlet flanges had different sizes and spatial positions, excluding the possibility of using standard sections. Our engineers developed individual working drawings (Fig. 6), strictly adapted to the requirements of the customer’s site, which made it possible to ensure a tight connection to existing air ducts without additional adapters.
Specifications and configuration
The engineered unit is a two-stage filtration system optimized for the tropical conditions of Southeast Asia.
Model: TCF-03.02BF04
Nominal air flow: 30,000 m³/h
Initial resistance: 180 Pa (at rated flow)
Overall dimensions: 1750 × 1900 × 1900 mm
Housing material: Galvanized steel with powder coating (anti-corrosion resistance).
Filtering configuration:
1.Stage I - Filter G4 (plate):Size 592x592x46 mm. Effectively traps coarse cement dust and fibers, protecting the second stage.
2.Stage II - Filter F9 (bag): Size 592×592×381 mm. Retains particles ≥1 micron in size, ensuring high air quality in workshops.
Production and quality control
The production cycle included not only assembly, but also aerodynamic debugging. The housing is equipped with a bilingual (Chinese and English) technical data plate (Fig. 3), which simplifies equipment identification and commissioning. Before shipment, leak tests were carried out and flange geometry was checked for compliance with the design documentation.
Logistics and packaging
Taking into account long international transportation, the equipment is packed in an export wooden box made according to ISPM 15 standard (Fig. 4, 5). This guarantees the safety of welds, filter inserts and paintwork during sea transportation.
Operation and Maintenance
Due to the high quality of manufacturing and accurate calculation of aerodynamics, at the time of shipment there is no need for post-warranty service. However, according to the technical documentation, the following regulations are recommended to ensure long-term effectiveness:
Replace G4: every 1–3 months (depending on the degree of contamination).
Replace F9: every 6–12 months.
Replacement criterion: achievement of a resistance of 360 Pa (2 times the initial value).
Conclusion
This project clearly demonstrates the competencies of TC Filter Group in the field of individual design of ventilation equipment for difficult industrial conditions. We provide a full cycle of work: from aerodynamic calculations and design design development to manufacturing and international logistics.
Similar engineering solutions for air filtration have already been successfully implemented for customers in Russia and the CIS countries (Moscow, Kazan, Almaty), where high demands are placed on air purity in metallurgy, pharmaceuticals and electronics.
