PL15 Oil/Water Separator

Name: PL15 oil/water separator
Brand: PURE Line by STERLING Separation
SKU: PL15

A unique concept in on-site condensate treatment for compressors up to 15 kW: 90 cfm (2.5 m³/min) at pressures below 16 barg, in a unit just 270 mm tall.

PURE Line

Small Compressor, Same Legal Duty

Over an 8,000-hour working life, even a small 11 kW compressor produces more than 7,500 litres of condensate carrying several litres of compressor oil, enough to de-oxygenate hectares of open water. Discharging it untreated is illegal, and having it collected by a licensed waste contractor is costly.

The PL15 treats that condensate at source for a fraction of the price. It is a different design from the rest of the PURE Line: a sealed, replaceable service cartridge inside a fixed outer body, so servicing is a twist, a lift and a swap.

Quick, secure installation, with wall and floor mounting hardware both included
Rapid, no-tools servicing: rotate the lid, lift it off, swap the cartridge
No overspray: four levels of protection keep untreated condensate away from the vents
Visual Time-in-Service (TIS) indicator
Up to 4,000 hours service life from an inexpensive PL15SK cartridge

Servicing

Cartridge Life Guide

How long a cartridge lasts depends on how hard the compressor works. Change it at whichever comes first: the months below, or the TIS indicator.

Annual run hours	2,000	4,000	8,000
Light duty	24 mo	18 mo	12 mo
Typical	21 mo	15 mo	9 mo
Arduous	18 mo	12 mo	6 mo

Time-in-Service indicator. A visual indicator clipped into the lid shows at a glance when the cartridge is due. A new TIS indicator comes with every PL15SK.

How it works

Condensate enters through the inlet, directed down and away from the air vents, into a de-pressuriser with a foam diffuser. Inside the cartridge:

Primary filtration removes the bulk oil
Polishing filtration traps the smaller oil droplets
Clean water leaves through the push-fit outlet. It always drains automatically, with nothing to adjust

What's in the box

Outer body, lid, cartridge and foam diffuser, fully assembled
Wall-mount bracket and optional floor-mount hardware
TIS indicator, polybag and installation & maintenance manual
