AK Series Precision Filter
Advantage
Features:
- The filter housing is made of aluminum alloy by die-casting and has a compact structure to ensure safe use.
- All housings are cleaned, degreased, and specially anti-corrosion treated before spraying to improve durability and applied to offshore platform operations.
- The precise threaded interface makes installation and maintenance more accessible and more convenient.
- All housings tested under working pressure 32bar for 96 hours, and the maximum burst pressure is 105bar.
- Under the working condition of 1.5-80 ºC and pressure 16 bar, the body is guaranteed 15 years, and the service life of the Filter Element is 6000-8000 hours.
DETAILS
DP Gauge
The most popular application for differential pressure gauges is filtration monitoring. As a filter cartridge becomes obstructed with contaminants, the pressure between the inlet and outlet ports increases, and efficiency drops.
When the differential pressure reaches a specific limit, the operator knows it is time to change the filter, keeping the process running smoothly and efficiently and preventing damage to the system. Similarly, the operator can use the DP gauge to detect scale buildup in pipes and pumps.
High Quality Body
All shells are cleaned, degreased and specially anti-corrosion treated before spraying to improve durability and can be applied to offshore platform operations. The precise threaded interface makes installation and maintenance easier and more convenient.
Sight Glass
Sight glass is made of unique materials, checks the blockage condition of the drainer
Manual Bleed Valve
The pressure can be relieved when the Precision filter is replaced or overhauled by rotating the manual Bleed Valve. You can also drain when the Auto drain valve is blocked with the manual bleed valve.
