Spare parts & components
Genuine OEM parts, delivered fast
When critical components need replacement, original parts protect system performance, ensure precise fit and compatibility, and reduce the risk of unplanned downtime — keeping your filtration system reliable throughout its lifecycle.
Expert part selection
Assistance choosing the correct parts the first time — no guesswork, no mismatched replacements.
Result: peace of mind through genuine OEM quality.
Direct regional shipment
Parts ship directly from regional stock to keep lead times short and production running smoothly.
Result: minimal downtime when it matters most.
Maintenance, lifecycle service & performance agreements
Predictable costs, maximum availability
Continuous, reliable operation takes more than routine maintenance. Our service programmes provide predictable costs, maximum availability and clear accountability — each agreement designed to minimise downtime, ensure compliance and safeguard your investment in critical APC assets.
Filter Bag Changes
Bag changes carried out by OEM service experts so your filter system keeps operating efficiently and safely.
- Replacement with original, process-matched filter media and cages
- Correct sealing and fit for leak-free performance
- Safe, efficient changes following local safety standards
Result: stable differential pressure, consistent low emissions and minimized downtime.
Inspection Agreements
Regular, structured inspections of all air pollution control equipment by experienced service experts.
- Complete checks: filter bags, cleaning system, fans, discharge, controls and safety devices
- Early problem detection to prevent failures and extend filter life
- Detailed, prioritised action plan for budgeting and shutdown planning
Result: documented system condition for every audit and lower risk of unplanned downtime.
Clean Air as a Service
Two ways to protect your investment
Choose extended warranty coverage on key components, or hand the whole system to our experts under a full maintenance contract.
| Feature | Extended Warranty | Full Maintenance Contract |
|---|---|---|
| Best for | Protecting key spare-part costs with predictable budgeting | Offloading all maintenance so your team focuses on core operations |
| Term | Up to 5 years of warranty — beyond industry standards | 5–10 year full maintenance contract |
| Cost structure | Predictable cost structure for key spare parts | One fixed monthly rate covering labor, parts and warranty |
| Coverage | Main components | Inspections, maintenance and defined repairs, including wear parts |
| Inspections | Bi-annual inspections required | Preventive service included |
| Monitoring | Includes MikroPul Assist monitoring | 24/7 monitoring and remote support |
| Reporting | Regular maintenance keeps systems efficient | Clear KPI reports from the OEM expert team |
Diagnostics, compliance & laboratory services
Turn operating data into verified results
When it comes to emissions compliance and system health, assumptions are risky. By combining field expertise with in-house laboratory testing, we help maintenance and EHS managers secure reliable performance, reduce environmental risk and plan maintenance with confidence.
Pre-Inspection & Dust Measurement
An EPA pre-inspection checks your system before official emission testing — measuring residual dust and detecting filter leaks.
- Mobile residual-dust monitoring
- UV-powder leak test to verify filter integrity
- Optional MikroPul Assist integration for ongoing monitoring
Result: avoid failed audits and receive a full report with corrective actions.
Laboratory Analysis of Filter Bags
Laboratory testing evaluates the condition of used filter bags to support proactive maintenance planning.
- Air-permeability testing and fibre-damage inspection
- Microscopic and contamination analysis (oil or dust load)
- Four service levels — basic visual check to full composite assessment
Result: timely replacements, lower emergency costs and consistent emission compliance.
Particle Size Analysis
Our in-house laboratory determines your actual dust particle-size distribution to verify that filter media and cleaning settings fit current conditions.
- Precision dry-sieve analysis with 0.1 mm resolution
- Detailed report with expert filter-media recommendation
- For asphalt, minerals, foundries and other high-dust industries
Result: prevent clogging and high Δp; base upgrades on verified data.
Modernizations, energy & process optimization
More performance, less energy
Our modernisation and retrofit solutions enhance performance, reduce energy use and extend equipment life — without the cost of a new system. Each upgrade is OEM-engineered to deliver measurable results, minimal downtime and long-term reliability.
Up to 60% energy savings
Variable Frequency Drive Retrofit
A VFD adjusts fan speed to process demand instead of constant full-speed operation, cutting energy use and mechanical wear.
- Up to 60% energy savings with ~1-year payback
- VFD cabinet with diagnostics and field installation
- May qualify for subsidies (e.g. BAFA in Germany: 30–40% funding)
Result: lower power use, quieter operation and extended fan life.
Future-proof your system
Control System Modernization
Obsolete Siemens S5 components are replaced with modern S7 hardware and software for reliable operation and spare-part availability.
- Program conversion and rewiring to S7 standard
- Module and compact control hardware replacement
- Functional testing, commissioning and updated documentation
Result: avoid downtime from discontinued parts; future-proof automation.
20–30% energy savings
Telescopic Pipe Conversion
Outdated cleaning hoses are replaced with height-adjustable telescopic pipes to improve reliability and reduce energy consumption.
- 20–30% fan energy savings potential
- One-day installation per filter system
- Full retrofit kit, documentation and CE marking
Result: simpler maintenance and ROI typically within 1–2 years.
Up to 10% energy savings
Cooler Bypass Conversion
Enables bypass operation of process gas coolers when cooling isn't required, reducing wear, energy use and pressure drop.
- Bypass damper or modified hood and piping options
- Configuration tailored to your existing cooler design
- Integrated control logic for safe operation
Result: lower maintenance and extended equipment life.
Longer Filter Life
Additive Dosing System
Reactive additives such as lime or coke are injected into the raw gas stream to neutralise pollutants and protect the filter media.
- Tailored dosing system with fan, dosing unit and mixing reactor
- Compatible with manual, big-bag or silo feeding
- PLC integration and synchronised operation
Result: longer filter life, reduced corrosion and better compliance.
30–80% lower investment
Plant Expansion & Modernization
When production increases, your existing filter system can be upgraded to handle higher air volumes through customized expansion.
- Add filter chambers, double-deck or parallel filters
- Upgrade fans, ducts and motors
- Integrate new components into existing PLC and controls
Result: 30–80% lower investment vs a new system, with shorter downtime.
