What is the flow rate range?

The flow rate ranges from 4 to 360L/S (63 to 1513gpm).

How does the foam bladder tank work?

Pressurized water flows through the proportioner, forcing foam concentrate out of the bladder to mix with water and form foam solution.

What is the lead time for orders?

Peak season lead time is one month, while off-season lead time is within 15 workdays.

AI-Powered supplier vetting

SummaryWinan is identified as a private manufacturer/factory in Shenzhen, China, specializing in fire-fighting equipment such as foam systems, sprinkler systems, fire monitors, hydrants, water-mist systems, and valves. The supplier reports ISO 9001:2000 and CCCF certifications, more than 25 years of industry experience, national patents, and membership in the Chinese Fire Protection Association. Export activity is documented since 2014, with exports representing 31%–40% of total sales and self-operated import/export rights. Production data specifically states capacity of 500 foam bladder tanks annually. However, the available information does not establish current contract status, inventory or overseas service capabilities, detailed financial credibility, customization services, or customer case references. The audit record is from 2024–2025, with an evaluation result recorded as 0, but the meaning of that result is not specified.
