Pureflow Bio · Skimmer foam handling
Foam Extractors for Protein Skimmers
Move collected foam away from your protein skimmer with Pureflow Bio foam extractors. The FE unit draws foam and gas from large skimmer collector heads, then separates the waste streams for onward handling.
Made in India for aquaculture, RAS and aquarium installations. Share your skimmer and operating details so we can confirm the right arrangement for your site.
What Do Foam Extractors Do?
A foam extractor is an accessory for handling the foam and gas collected at a protein skimmer’s head. It helps transfer this waste away from the collector to a separate handling point.
The skimmer performs the foam-fractionation process in the water stream. Meanwhile, the FE unit manages the material leaving its collector.
When ozone is used, the gas route needs separate treatment and monitoring. A dedicated outlet provides a connection point; it does not establish that the discharged gas is ozone-free.
Designed Around Your Skimmer Installation
Aquaculture and RAS
Handle foam from larger skimmer collectors in hatchery and fish-farm treatment systems. First, confirm the collector interface and expected waste load.
Public aquarium life support
Plan the foam-waste route alongside the skimmer and the wider life support system. Also allow space to inspect and clean the extractor.
Ozone-assisted skimming
Coordinate extraction with the complete off-gas system. Then confirm compatible materials, treatment equipment and controls in the quotation.
From collector to waste handling
How Foam Extractors Work
Draw foam from the collector
A waste-gas blower creates suction to move foam and gas from the skimmer head. In turn, the required suction depends on the connected pipework and operating load.
Separate the waste streams
The water-lock chamber separates liquid waste from the gas route. Meanwhile, a siphon at the water outlet maintains the intended water level.
Route gas and drainage
Send collected liquid to the agreed waste drain. Then, where ozone is present, connect the gas route to the specified off-gas treatment system.
Foam Extractors: Features and Connections
Blower-assisted extraction
The waste-gas blower draws foam away from the collector. Also confirm its duty point and electrical supply for the actual pipe route.
Water-lock separation
The chamber and siphon work together to control the liquid level. Therefore, drain elevation and any backpressure need checking during design.
Backflow prevention
The inlet arrangement includes backflow prevention. In addition, verify the valve orientation, inspection access and compatibility with the connected equipment.

Foam Extractors: Specifications
First, request a current FE datasheet for your installation. This page does not list a verified model-capacity table, so final ratings and dimensions are confirmed in your quotation and approved drawing.
Information Needed for FE Selection
| Selection item | Confirm for your installation |
|---|---|
| Skimmer interface | Skimmer model, number of connected collectors and connection sizes |
| Gas and foam load | Gas flow, its stated reference conditions, foam loading and simultaneous operation |
| Blower duty | Required suction, pipe length, fittings and downstream pressure losses |
| Construction | Body, seals, valves and blower materials for the stated water and gas conditions |
| Drainage | Siphon arrangement, drain elevation, waste volume and permitted backpressure |
| Installation | Overall dimensions, footprint, access and support requirements |
| Electrical supply | Voltage, phase, frequency, blower power in watts and control interface |
| Ozone service | Gas concentration and load, off-gas treatment, monitoring and control interlocks |
Confirm the Complete Scope of Supply
The FE arrangement brings together the extraction tower, waste-gas blower, inlet backflow prevention and siphon arrangement. However, the quotation must identify the actual supplied assembly and its connections.
Discuss pipework, controls and any off-gas treatment or monitoring equipment as part of the project. Therefore, these items are included only when stated in the agreed scope.
Request Current Datasheet & Options ↗Specifications and Pricing
Specifications and any published prices may change as equipment is updated. Before ordering, confirm the current technical details, regional electrical requirements and pricing with our team.
Optional components are quoted separately unless expressly included. Your quotation confirms the final configuration, scope of supply and delivery terms.
Integrating Foam Extractors into Your System
Plan the FE unit alongside the skimmer collector, drainage and any ozone system. First, confirm the connections and operating levels; then check access and the complete gas route.
Plan the Connections
- Match the extractor inlet to the skimmer collector connection.
- Confirm the blower duty against the complete gas pipe route.
- Provide the agreed siphon, waste drain and gas treatment connections.
- Finally, allow access to the chamber, valves and blower for inspection.
Keep the Waste Route Clear
Inspect the liquid level, siphon and drainage path as part of routine checks. Also check for foam carryover, deposits and changes in extraction performance.
Follow the supplied shutdown and isolation instructions before cleaning. Where ozone is used, follow the site’s ozone handling and maintenance procedure.
How to Size Foam Extractors
Start with the skimmer collector and the foam and gas it needs to discharge. Water-treatment flow or total tank volume alone cannot establish an extractor’s suction or waste-handling duty.
- Identify the skimmer model, collector connection and number operating together.
- Confirm gas flow at stated operating conditions and the expected foam load.
- Next, check required suction, pipe length, fittings and downstream pressure losses.
- Review siphon and drain levels, maintenance space, electrical supply and controls.
- Where ozone is used, specify the gas treatment and monitoring arrangement separately.
For different skimmer models or loads, send each duty and the proposed shared-pipe layout. The calculator below totals identical gas loads; final FE and blower selection needs a project review.
Foam Extractor Selection Brief & Gas-Flow Calculator
Use this tool to collect the details needed for a quotation. If gas flow is known, it totals the load from identical skimmers operating together. Otherwise, you can prepare a brief with the gas flow marked for confirmation.
How the gas-flow calculation works
Total gas flow = flow per skimmer × the number operating together. Next, the comparison load adds your chosen percentage allowance. For unit conversion, 1 L/min = 0.06 m³/h.
Use gas volumes stated at the same operating temperature and pressure. Therefore, standard or normal gas volumes need conversion before entry. For different skimmer loads, send the individual duties for review.
This arithmetic does not select a blower or an FE model. For example, blower selection requires suction and pressure-loss data, while ozone treatment requires its own gas-load and performance checks.

Foam Extractors: Common Questions
What is a foam extractor?
It is a vessel that collects the foam coming off a protein skimmer, lets it collapse into liquid waste and drains it away. It also gives the off-gas its own outlet, which you can route to an ozone destruct unit.
Why would I need one instead of a normal collection cup?
On large skimmers a collection cup fills quickly and someone has to empty it by hand. A foam extractor handles the foam continuously and sends the waste to drain, which matters on a fish farm or public aquarium running around the clock.
Does a foam extractor replace the skimmer?
No. The skimmer makes the foam; the foam extractor deals with it afterwards. They work as a pair.
Can it be used with ozonated skimmers?
Yes. Routing the skimmer's off-gas through the foam extractor to a destruct unit keeps ozone out of the plant room air.
Which foam extractor size do I need?
We match it to the skimmer it serves, mainly by the volume of foam and air coming off. Tell us your skimmer model or flow and we'll suggest the right extractor.
