Description

Chemguard 3% x 3% AR-AFFF is a specially formulated, free flowing, viscous, aqueous film forming foam concentrate. It forms a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels. Chemguard 3% x 3% AR-AFFF is intended for use at a proportioning rate of 3% (3 parts AR-AFFF to 97 parts water) on hydrocarbon fuels such as gasoline, kerosene, diesel, etc., and on polar solvent fuels such as alcohols, ketones, esters, etc. Chemguard 3% x 3% AR-AFFF is specifically formulated for Topside, or Type II and Type III applications.

FEATURES

• U.L. listed, Foam Liquid Concentrate
• Used at a 3% proportioning rate on both hydrocarbon and polar solvent fuels
• Suitable for use with either fresh or salt water
• Excellent wetting characteristics when used in combating Class “A” fuel type fires
• Suitable for use with fiberglass, polyethylene or stainless steel. 3% - 3% AR-AFFF is not compatible with galvanized pipe or fittings in an undiluted form.
• Suitable for use on hydrocarbon or polar solvent type fuels
• Suitable for use with both air-aspirating foam and standard water fog nozzles
• Economized for Topside applications

PROPORTIONING

• Fixed or portable in-line eductors
• In-line balanced pressures and pump pressure proportioning systems
• Around the pump proportioners
• Handline, air-aspirating nozzles with fixed eductor pickup tube

DISCHARGE DEVICES

• Foam Chambers
• Standard water fog nozzles for handlines and monitors
• Air-aspirating foam nozzles
• Foam makers for use with either Floating roof storage tanks or Dike/Bund protection systems

FOAMING PROPERTIES

Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% - 3% AR-AFFF is mixed with water at the correct ratio. Non-aspirating type devices will typically generate expansion ratios of between 2-4 to 1. Expansion ratios are dictated by the type of discharge device, flow rate and discharge pressure
