PL30, PL75, PL160, PL320 & PL480 Oil/Water Separators

PURE Line

Easy, Economical, Effective

The PL30, PL75 and PL160 treat condensate from systems of up to 200, 530 and 1,150 cfm (5.7, 15.0 and 32.6 m³/min). There is no weir and no stagnant standing water: condensate flows through the filter beds under gravity alone, and leaves at below 20 ppm.

Now with an average of 20% more capacity across the range, flared bases for stability, brass inserts in place of plastic threads, twin test points, a sample-jar holder and a Time-in-Service indicator in the lid.

No-tools servicing throughout

Up to 4,000-hour service life

Lifetime warranty across the PURE Line

Quality mouldings with brass fittings

Lightweight multi-part filters in the PL160

'AF' option for emulsions and PAG oils

Mid-treatment sample point

OEM and own-label options

STERLING PURE Line PL160 and PL75 separators with a PL15

Specifications

Choose by System Power or Air Flow

The model number is the maximum system power in kW. Capacities are for well-maintained plant on mineral lubricants.

Model	System power	Capacity (cfm)	Capacity (m³/min)	H × W × D (mm)	Dry weight (kg)	Service kit
PL30	30 kW	200	5.7	560 × 220 × 255	3.4	PL30SK
PL75	75 kW	530	15.0	750 × 310 × 335	4.5	PL75SK
PL160	160 kW	1,150	32.6	980 × 400 × 430	16	PL160SK
PL320 PLEQ3 + 2 × PL160	320 kW	2,300	65.1	980 × 900 × 430	35	PL320SK
PL480 PLEQ3 + 3 × PL160	480 kW	3,450	97.0	980 × 1,400 × 430	51	PL480SK

'AF' active filter variants have the same dimensions, with a 2,000-hour service life. AF kits carry an AF suffix (e.g. PL75SK/AF) and retrofit to standard units without modification. For PAG lubricants, use AF or reduce rated capacity by up to 50%.

How It Works

Gravity Does the Work

Condensate enters through four ½" BSP inlets into the pressure-relief chamber, where the compressed air expands safely.
The first filter traps particulate matter and removes the bulk of the oil.
The second filter polishes the flow, trapping smaller droplets to below 20 ppm. In the PL160 this filter is split in two, keeping each service part light and manageable.
Clean water discharges under gravity to the foul drain. No moving parts, no power, no adjustment.

Servicing made simple

Lift the lid, exchange the lightweight filter parts, clip in the new TIS indicator. Complete service kits PL30SK, PL75SK and PL160SK are dispatched same-day from stock.

Accessories

STD floor stand for the PL30 and PL75 raises the separator by about 300 mm where drain height demands it.

PL320 & PL480

Divided Systems, Built on the PL160

When a PL160 isn't quite big enough but the IBC-based PL550 is far more separator than the plant needs, fill the gap with a divided system. The PLEQ3 condensate flow divider splits one incoming line into two or three equal feeds, so a bank of PL160s shares the load evenly and each delivers its full rated performance and service life.

Equalised load. No lead unit taking the punishment, no early filter change
One spare to stock. Every vessel takes the same PL160SK service kit
Scalable. Start at PL320 and add the third vessel later, with no re-plumbing of the divider
Same cover. Lifetime warranty and the 'AF' option apply across the whole system

PLEQ3 at a glance

Working pressure	20 barg / 290 psi
Ports	3 × ½" in, 3 × ½" out
Dimensions	300 × 300 × 160 mm
High-pressure option	PLEQ3H, 45 barg / 650 psi

Wall-mount the divider with its outlets at least 750 mm above the separator inlets, and run equal lengths of ½" bore hose to each vessel on a steady fall. The PLEQ3 is not a pressure vessel.
