Production Capacity

This specification defines the volume of foam the machine can generate per unit of time, typically measured in liters or gallons per hour (L/h or GPH). It is a critical factor for matching machine output to application demands—such as fire suppression, insulation spraying, or cleaning operations.

Smaller units may produce 500–1,000 L/h, suitable for light-duty or mobile applications, while industrial-grade models can exceed 3,000 L/h. The actual output depends on motor power, mixing efficiency, and the type of foaming agent used. Always consider peak demand when selecting capacity to avoid bottlenecks.

Mixing Speed (RPM)

Mixing speed determines how quickly and effectively the machine blends water, air, and foaming concentrate to create stable foam. Most automatic batch foaming machines offer variable speed controls, allowing operators to adjust between 1,500 and 3,000 revolutions per minute (RPM) depending on the foam type.

Lower speeds are ideal for delicate foams requiring fine cell structure (e.g., Class A foam for firefighting), while higher speeds suit dense, high-expansion foams used in industrial spill containment. Precision control ensures optimal expansion ratios and consistency across batches.

Power Source and Electrical Requirements

The majority of automatic batch foaming machines are electrically powered, operating on standard industrial voltage levels of 220–240V. Power consumption generally ranges from 1 to 5 kW, depending on motor size and production capacity.

Some portable or remote-site models may feature diesel-powered generators or pneumatic drives for off-grid operation. When installing, ensure electrical circuits can handle startup surges and include proper grounding and circuit protection to prevent damage and ensure operator safety.

Dimensions and Weight

Physical size and weight impact mobility, installation space, and transportation logistics. A typical large-capacity unit measures approximately 1,200 × 800 × 1,800 mm (L×W×H) and weighs around 120 kg, though heavier industrial versions may exceed 200 kg.

Compact models are available for mobile firefighting units or tight workspaces. Consider access points, floor load capacity, and whether the machine requires permanent mounting or frequent relocation when evaluating footprint and weight.

Ingredient Dispensing System

This system controls the precise delivery of foaming concentrate into the mixing chamber. Two primary types exist: pneumatic (air-driven) and gravity-fed systems, though some advanced models use metering pumps for higher accuracy.

Pneumatic systems offer better control and are less prone to clogging, making them suitable for viscous agents. Gravity-fed systems are simpler and cost-effective but may require manual adjustment. For consistent foam quality, look for models with adjustable flow rates and integrated level sensors.
