The Sentinel Eliminator Vortex 300 (MPN V300-GRP22-EXP) is a compact in-line magnetic filter designed for standard domestic central heating systems, ideal for installations where space is limited such as under a boiler. Using Sentinel's Vortex Core technology, it reduces water flow rate and turbulence within the unit to maximise contact time between circulating debris and a powerful neodymium magnet, capturing both magnetic and non-magnetic contaminants without ever blocking the system.
22mm Compression
Connection
KIWA / BuildCert
Certification
Compact Installation
Specifically suited to compact installations such as under-boiler fitting in standard domestic systems, where a full-size Vortex 500 or 700 filter may not fit available pipework space.
Certified Performance
Certified to KIWA / BuildCert (NSF) standards, giving installers independent assurance of the filter's debris-capture performance.
Servicing Note
Fitted with an anti-tamper drain valve and dual seals designed to avoid replacement at annual service; always isolate the system fully before opening the filter housing for inspection or debris removal.
Vortex Core Technology
The unique Vortex Core reduces water flow rate and turbulence within the unit, maximising contact time between circulating debris and the internal magnet for improved capture efficiency.
Dual Debris Capture
Combines magnetic filtration with sieve-based capture to remove both magnetic sludge and non-magnetic debris circulating in the heating system.
Never Blocks
The Vortex Core design ensures the filter will never block; collected debris can simply be flushed away via the drain valve without dismantling the unit.
Compact, Space-Saving Footprint
Designed as the more compact option in the Eliminator Vortex range, well suited to tight installation spaces such as directly under a boiler.
360° Adjustable Installation
A 360° positionable T-piece allows flexible in-line installation to suit a variety of pipework orientations and tight spaces.
Dual Seals, No Annual Replacement
Equipped with dual seals with no requirement to replace at annual service, reducing ongoing maintenance costs over the filter's working life.

What is the Vortex Core and how does it help?
The Vortex Core reduces water flow rate and turbulence within the filter, maximising contact time between circulating debris and the internal magnet, which improves debris capture and ensures the filter will never block.
Is this the compact or standard-size filter?
The Vortex 300 is the more compact model in the Eliminator Vortex range, designed for tight installation spaces such as under a boiler, compared with the larger Vortex 500 and Vortex 700.
What pressure is this filter rated for?
It has a maximum operating pressure of 4.5 bar.
Does this filter need its seals replaced every year?
No. It is equipped with dual seals with no requirement to replace at annual service.
Is this filter independently certified?
Yes, it meets KIWA / BuildCert (NSF) certification standards.
What connection size does this model use?
This variant uses 22mm compression valves. The Vortex 300 range is also available in 3/4" male and female connections.
