What is the VCFD type 1 draft capability using a 4" intake?

The draft capability of a VCFD Type 1 engine using a 4-inch intake is commonly understood to be in the range of 600-800 gallons per minute (GPM). This range reflects the ability of the engine to effectively draw water from a static source, such as a pond or tank, using the 4-inch intake configuration. The design of a Type 1 engine, which typically includes a powerful pump, larger diameter intakes, and robust operational capacity, enables it to sustain high flow rates essential for effective firefighting operations. Therefore, the specified capabilities from the 600 to 800 GPM reflect both the engine's design specifications and its operational effectiveness in maximizing water flow under draft conditions. Other ranges do not align with the operational standards set for this type of firefighting equipment.
