Yanmar 30 and 40 kW diesel generators
Two open diesel generators with a Yanmar engine, designed for mobile spray foam insulation rigs (spray polyurethane foam). EPA Tier 4 Final engine, genuine Stamford alternator, 120/240 V single phase. Available on request.

Two power ratings
For mobile spray foam insulation rigs and trailers
Spray foam insulation contractors install their generator in their work truck or trailer. These open Yanmar generators are made for that:
- Open, compact model, easy to fit into the rig
- 120/240 V single phase for the rig’s electrical equipment: spray machine, heated hoses, compressor
- Yanmar Tier 4 Final diesel engine, built for long work days
- Engine block heater included for cold-weather starts
Tell us what equipment your rig runs: we confirm the power you need, 30 or 40 kW, in the quote.
Spray foam, spray polyurethane foam (SPF), spray foam insulation: it is all the same insulation, and the mobile unit is called a spray foam rig or spray foam trailer. In Quebec, contractors call it uréthane, uréthane giclé or mousse de polyuréthane giclée.

Why a Tier 4 Final engine?
Tier 4 Final is the most recent EPA emission standard for diesel engines. The engine emits far less particulate matter and nitrogen oxides than a Tier 3 engine. The Yanmar engine, with common-rail direct injection and an electronic governor, also meets the European Stage V standard. It is a good choice when your project calls for the latest equipment.
