Honda GX versus GC Engines

Posted by Ventry Solutions, Inc. on

Effective the end of 2021, Honda discontinued production of certain general-purpose engines, including the GC160, in order to focus their production on new models. Due to this, Ventry Solutions, Inc. has discontinued Ventry Fan Models 20GC160 and 24GC160.

What is the difference between the Honda GX and GC series engines?

VENTRY Fans with GC160 engine and GX200 engine

Ventry® Ventilation Fans, patented portable gas and electric fans used primarily in fire fighting and brush burning / slash pile burning, now utilize Honda GX-series engines (effective January 2022). Prior to 2022, Ventry Fans also utilized Honda's GC160 motor, but discontinued those models when Honda stopped production of the GC-series engines. Since many of the GC-series motors are still in use, below is a comprehensive overview of the main differences between Honda's GX- and GC-series motors.

GX-Series GC-Series
Suggested Type of Use Commercial Residential [1]
Low-Oil Shut-Off (prevents damage to the engine) Yes No
Engine Material Mostly metal Mostly plastic
Bore Material Cast iron (giving GX-series motors longer life) Aluminum
Fuel-Shutoff Valve [2] Yes No
On/Off Switch [3] Yes Yes, combined into the throttle control
Place of Origin Thailand (subject to change) USA
Warranty (commercial use) 3 years 3 months

A bonus of the GX-series engines when used with Ventry Fans, is that models 20GX160 and 24GX160 (each consisting of a GX160 motor) are available with an integral power supply unit used to run a halogen or LED Point of Entry (POE) Safety Light. Since the POE Safety Light is wired directly to an alternator in the engine, it was not available on the economy GC160 or as an add-on to existing Ventry Fans.

[1] GC-series engines can be used in commercial equipment, but the warranty period will be shortened.
[2] A major benefit of the fuel-shutoff valve is that if the motor is run infrequently, the fuel can be run out, which is easier on the carburetor. Also, shutting off the fuel valve prevents the accidental mixing of oil and fuel, which can happen if the motor is jostled a lot (for example, when a fan is carried on a truck over a bumpy road).
[3] Having the on/off switch combined in to the throttle control (as with the GC motors) makes for simpler operation, but it has the drawback of not being able to run the fuel out of the carburetor.
