Impco Cobra Vaporizer for Forklift

The IMPCO Cobra is a two-stage propane converter/regulator (vaporizer) designed for LPG (liquid or vapor) fuel systems including forklifts, vehicles, industrial or stationary equipment. It improves upon the older IMPCO “Model J” by incorporating enhanced design features to improve reliability, cold-weather performance, and resistance to contamination and failure.

Key Features

• Two-stage operation with a primary stage (high pressure) and secondary stage that produces a small negative outlet pressure (standard −1.5″ WC)

• Fluorosilicone diaphragm in the secondary stage for better resistance to heavy LPG oils and adverse conditions

• Improved primary seat and orifice for reduced tendency to freeze up or clog from fuel impurities

• Multiple secondary spring options for varying negative outlet pressure: standard blue spring (−1.5″ WC), optional orange spring (−0.5″ WC)

• Fuel filtration requirement: 40 micron filtration to protect internal components

• Wide operating temperature range: from −40°F up to +250°F (approx. −40°C to +121°C)

• Certified for LPG service and built tough for mobile, stationary, and industrial applications

Specifications

Applications

• Forklift propane systems needing reliable vaporization and pressure regulation

• Mobile or vehicular LPG applications where consistency and resistance to freezing or soot are important

• Stationary or industrial equipment running off propane liquid/vapor feed

• Environments with severe cold or marginal fuel quality where better diaphragm and filter protection help maintain performance

Why Choose IMPCO Cobra

The Cobra offers several improvements over older LPG converters — more durable materials, better resistance to contaminants and cold, and more consistent negative outlet pressure. It’s built for long service under tough conditions and is a good upgrade for any propane-powered mobile or industrial engine currently using older “Model J” or similar converters.
