Maintenance
Maintenance contracts for extraction and ventilation systems
GAKO maintains extraction and filtration systems in industrial plants, including systems installed many years ago and systems installed by others. Every visit is scheduled in advance and carried out on the agreed date, and the work is done thoroughly until the system is extracting properly again.
Service principles
Maintenance that starts with scheduling and continues for years
GAKO's maintenance contract rests on the working principles that guide us in every plant, and we follow them on every visit.
- Every visit scheduled in advance with the maintenance and operations manager
- Arrival on the agreed date
- A report on any defect found during the work, including defects outside the scope of the order
- Complete and thorough work, including on systems that have run for many years
- Support for the system for years after installation
What the contract includes
Maintenance contract components
- Scheduled inspections at a frequency set in the survey, by system type and load
- Differential pressure measurement across the filters, with replacement as needed
- Cleaning of ducts, hoods and filter housings
- Fan checks: motor, belts, bearings, vibration and noise
- Repair of faults found during inspection
- A written record of every visit, and a filter replacement certificate after every change
- An annual maintenance agreement that can be presented to the environmental authorities, for plants that require one
What an inspection covers
| Component | What we check | What we do |
|---|---|---|
| Filters and bags | Differential pressure, damage and leaks | Replacement per the manufacturer's instructions |
| Ducts | Dust or grease build-up, leaks and joints | Cleaning and repair |
| Fan and motor | Vibration, noise, belt tension and bearing condition | Adjustment, lubrication and component replacement |
| Extraction points | Actual capture at the workstations | Damper balancing and repair |
| Controls | Operation of sensors, relays and alarms | Calibration and repair |
The frequency and scope of inspections are set in the first survey and written into the contract.
