The Right Foam, The Right Place, The Right Way

Foam suppresses Class B fires through three combined effects: cooling the fuel surface, separating fuel vapour from atmospheric oxygen with a sealed blanket, and re-sealing the surface against re-ignition. The right foam expansion ratio depends entirely on the fire scenario — a refinery tank rim fire and a tunnel ventilation fire call for very different foam.

CA-FIRE manufactures three distinct families of handheld foam nozzles plus standalone inline foam eductors:

(1) Type A air-aspirating nozzles (PQA600, PQA Large Orifice) — heavy-flow nozzles for petroleum tank, ground fuel and Class A solid fires. (2) Low- and medium-expansion air-aspirating nozzles (PQ 2, PQZ8/0.8) — engineered for specific expansion ratios with K-factor verified performance for fixed-system specification. (3) Self-inducting foam nozzles with built-in eductor (QP4/0.7Z, QP8/0.7Z, QP16/0.7Z) — draw foam concentrate directly through a flexible suction tube, no upstream proportioner required. Plus standalone inline foam eductors (FE095, FE125, FE250) that convert any standard nozzle in your fleet into a foam-capable line.

How Firefighting Foam Is Made

Three ingredients combined at the correct ratio at the nozzle. Each CA-FIRE family handles this differently.

💧
Step 1

Water Supply

Pumped from hydrant or tender at line pressure.

🧪
Step 2 · Proportioning

Concentrate Added

Inline eductor (FE) or self-inducting tube (QP) mixes 1%, 3% or 6% foam concentrate.

💨
Step 3 · Aeration

Air Aspirated

Type A or expansion nozzle draws in atmospheric air through aeration ports.

🌫️
Step 4

Expanded Foam

Finished foam discharged onto the fire — cool, seal, smother.

Family A — Type A Air-Aspirating Foam Nozzles Tank Fires

Type A foam nozzles are heavy-flow air-aspirating nozzles designed for direct attack on petroleum tank fires, ground oil and oil-product fires, and Class A solid material fires. They are paired with an upstream proportioner or foam concentrate source. Suitable for general solid material fires when filled with water-only as well.

PQA (Large Orifice) 7 bar Pressure-dependent 28 / 32 mm 36 mm ≥15 m ≥18 m — / 1.5″ · 2.5″

Family B — Low & Medium Expansion Foam Nozzles Engineering Spec

Air-aspirating foam nozzles with certified expansion ratio and K-factor — for engineered fixed and mobile systems where finished foam properties must meet specification. Low-expansion (ratio ≥9) delivers dense long-throw foam for liquid-surface attack. Medium-expansion (ratio 20–200) delivers fluffy fast-filling foam for enclosed spaces.

Model Family Pressure Flow Expansion Ratio K Factor Drainage Time Throw
PQ 2 Low Expansion 0.8 MPa 120 LPM ≥ 9 43.4 ≥ 15 m
PQZ8/0.8 Medium Expansion 0.8 MPa 475 LPM (+10%) 20 ≤ N ≤ 200 50% in 20 min ≥ 18 m

Family C — Self-Inducting Nozzles & Inline Foam Eductors No Proportioner

Two solutions to the same problem — "how do I add foam without rebuilding my pump system?" QP-series foam nozzles have a built-in eductor and a flexible suction hose that draws concentrate from a portable container next to the operator. FE-series inline foam eductors are mounted in any standard hose line and convert any handheld nozzle into a foam-capable nozzle at the chosen proportioning rate.

Picking the Right Foam Nozzle

Petroleum Tank & Bund Fires

Atmospheric storage tanks (gasoline, diesel, crude) and the surrounding bund area need dense low-expansion foam that throws far and clings to the fuel surface. The PQ 2 air-aspirating nozzle delivers ratio ≥9 foam with a 15-metre reach; for higher flow the QP16/0.7Z (960 LPM, 33 m reach) is the workhorse. Pair with 3% or 6% AFFF concentrate.

Recommended: PQ 2 · QP16/0.7Z
🏭

Chemical Plants & Polar Solvents

Polar solvents (alcohols, ketones, esters) destroy ordinary AFFF foam — they need AR-AFFF concentrate paired with a robust air-aspirating nozzle. The PQA600 Type A nozzle and PQA Large Orifice deliver the heavy flow needed for plant process-unit fires, where the goal is rapid blanket coverage rather than long-throw attack.

Recommended: PQA600 · PQA Large Orifice
🚇

Tunnels, Basements & Enclosed Spaces

Medium-expansion foam (ratio 20–200) is the right tool when you need to fill a volume with fire-suppressing foam — vehicle tunnels, basement car parks, machinery rooms, oil-fired boiler enclosures. The PQZ8/0.8 expands 475 LPM of foam solution into 9,500–95,000 LPM of finished foam — filling a typical service tunnel within minutes.

Recommended: PQZ8/0.8
🚛

Fuel Spills & Tanker Incidents

Roadside fuel spills and overturned tankers need a fast deployment: foam ready in minutes, no time to rig a proportioner. The QP8/0.7Z self-inducting nozzle has a built-in eductor and a flexible suction tube — drop the tube into a 20 L AFFF can and start producing foam. 480 LPM at 33 m reach is sufficient for most highway incidents.

Recommended: QP8/0.7Z

Retrofitting Existing Hose Lines

If you already operate a fleet of standard water nozzles and want to add foam capability without buying new nozzles, install an inline FE-series eductor upstream. The FE095 / FE125 / FE250 mount mid-line, draw concentrate from a portable container, and feed foam solution to any handheld nozzle downstream. Adjustable 0–6% proportioning.

Recommended: FE095 · FE125 · FE250

One-Person Reel-Line Response

Compact response trucks and aircraft rescue units need foam capability without two-operator workload. The QP4/0.7Z (240 LPM, 2.7 kg) is single-operator, self-inducting, and reaches 30 m — ideal for compact fire vehicles, light tenders and small ARFF crews on small aircraft incidents.

Recommended: QP4/0.7Z

Frequently Asked Questions — Foam Fire Nozzles

What is a foam fire nozzle and when do I need one?
A foam fire nozzle is a handheld fire fighting nozzle that mixes air into a water-foam-concentrate solution to produce expanded firefighting foam. Foam is required for Class B fires — flammable liquids such as petroleum, diesel, ethanol, and chemical solvents — where plain water either fails to suppress the fire or actively spreads it. The foam blanket cools the surface, separates the fuel from oxygen, and seals back vapour release. See our blog article Foam vs Water for Class B Fires for a full breakdown.
What is the difference between low-expansion and medium-expansion foam nozzles?
Expansion ratio is the volume of finished foam divided by the volume of foam solution used to make it. Low-expansion (ratio 2–20) produces a dense, heavy foam that throws long distances (≥15 m on the CA-FIRE PQ 2) and clings well to vertical surfaces — used for petroleum tank fires and ground fuel spills. Medium-expansion (ratio 20–200) produces a much lighter, fluffier foam that expands 8 to 10 times faster (CA-FIRE PQZ8/0.8) — used to fill enclosed spaces like basements, tunnels and machinery pits where blanket coverage is more important than throwing distance.
What is the difference between an air-aspirating foam nozzle and an inline foam eductor?
An air-aspirating foam nozzle (Type A like CA-FIRE PQA600) is the discharge end of the system — it draws air into the foam solution stream to produce expanded foam at the nozzle. An inline foam eductor (CA-FIRE FE095, FE125, FE250) is mounted upstream in the hose line — it draws foam concentrate from a separate container into the water stream to create the foam solution that the nozzle later expands. A self-inducting foam nozzle (CA-FIRE QP4/8/16) combines both functions in one device: it inducts foam concentrate from a suction tube AND aspirates air at the discharge — no upstream proportioner required.
What foam concentrate works with CA-FIRE foam nozzles?
CA-FIRE foam nozzles are compatible with all standard low-expansion foam concentrates: AFFF (Aqueous Film-Forming Foam, 1% / 3% / 6%), AR-AFFF (Alcohol Resistant, for polar solvent fires such as ethanol and methanol), FFFP, FP (protein foam), and Class A wetting agent. The PQZ8/0.8 medium-expansion nozzle is optimised for AFFF 3% and 6%. We manufacture matched foam concentrate — see our foam concentrate range for a one-system supply solution.
What is foam proportioning (1% / 3% / 6%)?
Proportioning is the percentage of foam concentrate mixed into the water stream to form foam solution. For example, 3% proportioning means 3 litres of concentrate per 100 litres of water. CA-FIRE inline eductors (FE095, FE125, FE250) are field-adjustable for 0–1/4%–1/2%–1%–3%–6%. The QP4/8/16 self-inducting nozzles use a suction tube that draws directly from the concentrate container. Class A water-additive systems use very low ratios (0.1–1%); Class B AFFF typically uses 3% or 6% depending on the fuel. AR-AFFF on polar solvents is generally 3% or 6%.
What pressure do CA-FIRE foam nozzles require?
The Type A PQA600, self-inducting QP series and PQA Large Orifice all operate at 7 bar (≈100 PSI) standard handheld nozzle pressure. The low-expansion PQ 2 and medium-expansion PQZ8/0.8 air-aspirating nozzles operate at 8 bar (0.8 MPa). The inline foam eductors FE095, FE125 and FE250 are rated for optimum performance at 14 bar (≈200 PSI) inlet pressure — they need higher pressure because the eductor venturi consumes 30–40% of the inlet pressure to draw concentrate from the suction tube.
Can a foam nozzle be used as a water-only nozzle?
Yes for Type A and self-inducting nozzles when the foam concentrate suction tube is removed or the supply container is empty — they will discharge water with air aspiration but no foam expansion. The PQ 2 low-expansion and PQZ8/0.8 medium-expansion nozzles are engineering-spec products with calibrated foam-handling internals and are not optimised for water-only operation. For dedicated water nozzles see our adjustable flow rate nozzle range.
What standards do CA-FIRE foam nozzles meet?
CA-FIRE foam nozzles are designed and tested to Chinese national standard GB 18428 and are compatible with NFPA 11 (Standard for Low-, Medium-, and High-Expansion Foam) installation specifications. All products are manufactured under ISO 9001 quality management with 100% pressure testing before shipment. Full test certificates, expansion ratio test reports and CAD drawings are provided for every order. PICC product liability insurance covers all shipments.
What is the lead time and minimum order quantity?
There is no minimum order — CA-FIRE supplies single units for project replacement as well as bulk orders. Standard lead time for stocked foam nozzle models is 7–15 working days ex-factory Fujian. For OEM (custom laser engraving, packaging, colour, non-standard coupling, custom proportioning ratios on eductors) lead time is typically 25–40 working days.
