Change-out labour eliminated
No consumable element and no scheduled shutdown — most installations recover their capital premium within eighteen to thirty months on labour alone.
AXIS Series
Automatic backwashing and mechanically scraped filters that clean on differential pressure, time or flow — losing under 1% of throughput to purge.

Overview
Continuous filtration without a change-out schedule.
Manual filtration has a hidden cost that never appears on the purchase order: the labour, downtime and disposal of every change-out for the life of the plant. On high-solids duty running continuously, that cost overtakes the capital cost of an automatic filter within eighteen to thirty months.
The AXIS series cleans on demand. A differential pressure transmitter triggers the cycle, a motorised scraper or reverse-flow nozzle sweeps the screen, and the concentrated solids exit through a purge valve in eight to fifteen seconds. Forward flow is never interrupted.
Where the process cannot tolerate any purge loss, the AXIS-R configuration returns purge liquid to a small recovery loop with a bag filter, recovering better than 95% of the discharged volume and reducing net loss to a rounding error.

Advantages
What this platform does that a catalogue item does not.
Cleaning without flow interruption
Forward flow continues throughout the backwash cycle, so downstream equipment never sees a pressure or flow transient.
Purge loss under one percent
Nozzle geometry concentrates the backwash on the loaded screen segment instead of flooding the entire element.
Plant-integrated control
Modbus TCP, Profinet and Ethernet/IP are standard, so differential pressure and cycle counts land in your DCS as live tags.

FAQs
Questions engineers ask about self-cleaning filters
Roughly when manual change-outs exceed one per week on a continuously running line. At that frequency, labour, downtime and disposal typically recover the capital premium in eighteen to thirty months.
