Key Equipment for Spray Foam Insulation Contractors

By Kevin Malone

Investing in the right type of equipment needed for spray foam insulation application can help you build a profitable and rewarding spray foam business. Whether you are working solo or have crews working for you, making sure you have the right mix of industrial spray foam insulation equipment is crucial to completing jobs safely and consistently.

Here is a guide to the key components you need to power your contracting business.

Equipment Needed for Spray Foam Insulation

Proportioners and Reactors

At the heart of any spray foam rig is the proportioner unit. This machinery combines the insulation components during application to activate the foam. Proportioners meter the required ratio of the liquid materials and blend them as they pass through the reactor before discharging to the spray gun.

Units with higher processing capabilities allow insulation to be applied faster with less downtime between batches. Electric, hydraulic, or diesel-powered proportioners offer output rates ranging from 20 to 60 pounds per minute.

Spray Foam Guns

The spray foam gun serves as the final applicator to discharge mixed insulation onto project surfaces. Select durable, industrial-grade spraying guns from leading manufacturers specialized in insulation equipment.

Heated Hoses

Heated hoses connect proportioners to spray guns. Quality insulated hoses maintain the material temperature and spray pattern as foam components pass from tanks through proportioners and onto project surfaces.

Transfer Pumps

Transfer pumps move raw chemicals from drums, totes, or tanks to your proportioner. Electric or air-powered transfer pumps suited for viscous liquids make material loading safe and mess-free.

Drum Heaters

Pre-heating foam component chemicals improves blending, maximizes yield, and enhances spray performance. Drum heaters raise and maintain the temperature of materials stored before transfer into proportioner tanks.

Quality drum heating bands and blankets deliver adjustable, uniform heat suited for insulation chemicals without risks of overheating.

Air Compressors

Air compressors provide power for air-driven proportioners and tools. Projects where you have to move equipment frequently will benefit from towable trailer-mounted compressors. Multistage electric or gas compressors offer durable performance in outdoor job site conditions.

Select compressor capacities that exceed the peak air demand from the greatest combination of simultaneous tool use.

Safety Equipment

Spray foam safety gear includes personal protective equipment (PPEs) and respirators to protect crews. Contractors must provide proper safety equipment for all workers and enforce consistent, correct usage on all projects.

Provide comfortable, well-fitting PPE that allows mobility. Required basics include spray suits/coveralls, nitrile gloves, and ankle-high rubber boots for wading through applied foam. Supplement with hard hats, eye shields, and knee boards as warranted.

Properly fitted and maintained NIOSH-approved fresh air respirators with formaldehyde cartridges constitute mandated breathing protection.


Generators can eliminate the need for shore power for off-grid operation. Trailer configurations or trucks with on-board generators allow you to be self-sufficient. Stationary setups also benefit from backup power when relying on either single-phase or 3-phase wall current.

Specify generator output and receptacles to meet full demand from the proportioner, compressor, and ancillary tools simultaneously. Consult equipment manuals to calculate electrical loads for sizing generators appropriately.

Air Dryer

Moisture compromises spray foam set and performance. Air dryers installed downstream from compressors remove the humidity that condenses during compression cycles. This protects the foam from moisture contamination via the proportioner and tools.
