What foam types work with the 120L mobile foam unit?

The 120L mobile foam unit is compatible with several common fire-fighting foam types, tailored to its portable, small-scale emergency use.

First, Class A foam (for solid combustible fires like wood or fabric) works well: it boosts water's penetration and adhesion, letting foam cling to burning materials-ideal for the unit's flexible deployment in small solid-fire areas.

Second, aqueous film-forming foam (AFFF) suits flammable liquid fires (e.g., gasoline). It spreads fast to form a suffocating film over liquids, matching the unit's fast-response need for small liquid-leak fires, and mixes easily via the unit's proportioning system.

Third, synthetic foam (SFFF)-eco-friendlier than AFFF-fits scenarios prioritizing low environmental impact, while still suppressing liquid fires effectively.

All these foams require 3%/6% water mixing (matching the unit's system); incompatible, high-concentration foams are avoided to prevent clogging, covering most common fire scenarios for the unit's design.

mobile foam unit 120 ltr--How long can the 120L unit run continuously?

The continuous running time of the 120L mobile foam unit depends on its foam discharge rate and tank capacity (the 120L refers to its pre-mixed foam solution storage).

Typically, this unit has a discharge rate of 10–12L per minute. At this speed, the 120L solution allows continuous operation for about 10–12 minutes. If the discharge rate is adjusted to a lower 8L per minute (for smaller fires), the running time can extend to 15 minutes. Conversely, high-pressure, large-flow output (around 15L per minute) shortens it to 8 minutes.

Minor variations may occur due to foam viscosity, but the unit's running time generally ranges 8–15 minutes, fitting its small-scale emergency fire-suppression scenarios.

How often to maintain the 120L mobile foam unit?

More details

Daily Quick Inspection

Perform a daily visual check on the 120L mobile foam unit to ensure basic functionality. Inspect the exterior tank for dents, cracks or leakage, and check the hoses and nozzles for blockages or wear. Verify that the valve handles turn smoothly without sticking, and confirm the unit's wheels are in good condition for easy movement. This quick check takes only 5–10 minutes and helps spot minor issues early before they escalate into bigger problems that affect emergency use.

Monthly In-Depth Check

Conduct a comprehensive monthly maintenance check on the 120L mobile foam unit. First, check the foam solution's condition, ensuring it has no sediment or discoloration that indicates deterioration. Test the unit's discharge function briefly with clean water to confirm smooth flow through the hoses and nozzles. Lubricate the valve stems and wheel axles with appropriate grease to prevent rust and jamming. Finally, clean the entire unit to remove dust and debris that may accumulate during storage.

Annual Comprehensive Maintenance

Carry out a full annual maintenance overhaul on the 120L mobile foam unit. Disassemble key components including the nozzle, valve core and proportioning system, cleaning each part thoroughly to remove hidden residue. Replace any worn or aging parts such as seals, gaskets and hose connectors to restore optimal performance. Drain and replace the foam solution entirely, even if it has not been used up, to ensure freshness and effectiveness. Document all maintenance details for future reference and tracking.

How to refill foam solution in the 120L mobile foam unit?

mobile foam unit 120 ltr– How to refill foam solution in the 120L mobile foam unit?

Pre-Refilling Preparation & Inspection

Before refilling, confirm the unit is placed on a flat, stable surface and the main valve is fully closed to prevent spills. Check the 120L tank interior for debris or sediment and clean it with clean water if needed. Prepare the compatible foam concentrate (Class A or AFFF) and clean tap water, along with a measuring container to ensure accurate proportioning. Also, wipe the tank's filling port to avoid contaminating the new solution with dust or dirt.

Foam Solution Proportioning

Calculate the ratio of foam concentrate to water-typically 3% or 6% based on the foam type. For a 3% mix, measure 3.6L of concentrate and 116.4L of water; for 6%, use 7.2L of concentrate and 112.8L of water. Pour the concentrate into a clean mixing bucket first, then add water gradually while stirring gently to avoid excessive foam. Do not shake violently, as it can create unstable foam that affects fire suppression efficiency.

Safe Solution Injection

Open the tank's filling port cover and place a funnel at the opening to prevent splashing. Slowly pour the pre-mixed foam solution into the 120L tank, stopping when the liquid reaches the marked 120L level-leave a small gap to accommodate thermal expansion. Avoid overfilling, as it may cause leakage during transportation or operation. After pouring, rinse the funnel and dispose of any leftover solution properly instead of pouring it down drains.

Post-Refilling Check & Sealing

Tighten the filling port cover securely and wipe any spilled solution on the unit's surface. Open the main valve slightly and activate the unit for 5–10 seconds to circulate the solution, checking for leaks at connections and valves. Confirm the solution flows smoothly through the nozzle without blockages. Finally, record the refilling date, foam type and proportion for future maintenance reference, ensuring the unit is ready for emergency use.
