What air compressors are commonly used in construction?
Construction projects typically rely on gas-powered air compressors delivering 10–30 CFM for framing, roofing, and light commercial work, as they offer portability and strong output on outdoor jobsites. Electric air compressors in the 5–15 CFM range are more common for indoor renovations and finish work where noise, ventilation, and emissions are a concern.
What is the best gas air compressor for construction work?
The best gas air compressor depends on the application. Framing and carpentry usually require 15–20 CFM portable units, while roofing or multi-crew operations benefit from 20–30 CFM models. Contractors should prioritize reliable engines, durable pumps, and jobsite-ready construction designed for frequent transport and continuous use.
How much CFM does a construction air compressor need?
CFM requirements vary by tool and crew size:
- Single-user framing: 10–15 CFM
- Multi-crew framing: 20–30 CFM
- Heavy tools such as breakers and sanders: 25–50+ CFM per tool
Adding approximately 30% extra capacity helps maintain consistent performance and avoid pressure drops during extended operation.
Are diesel air compressors better than gas for construction?
Diesel air compressors are better suited for large-scale or continuous-duty projects due to their fuel efficiency, longevity, and ability to deliver sustained high airflow. Gas models are generally lighter, more affordable, and easier to service, making them a practical choice for residential and light commercial construction.
What size air compressor is needed for jackhammers?
Jackhammers typically require 25–50 CFM, depending on size and duty cycle. Smaller breakers may operate around 30 CFM, while heavy-duty jackhammers often need 45–50+ CFM with continuous output to perform efficiently without stalling.
What CFM is required for pneumatic nail guns?
- Framing nailers: 6–9 CFM
- Roofing nailers: 4–7 CFM
- Finish and brad nailers: under 4 CFM
Single users can work with smaller units; crews need higher CFM to avoid pressure drops.
How much CFM is needed for concrete tools?
Concrete breakers and drills generally require 30–50 CFM, while concrete vibrators typically need 15–25 CFM. Mixed concrete applications often demand 50+ CFM sustained airflow to support continuous operation.
What size compressor is needed for sandblasting?
Sandblasting requires very high airflow:
- Small nozzles: 50–100 CFM
- Larger nozzles or continuous blasting: 100–175+ CFM
These applications usually require high-CFM, trailer-mounted compressors, often diesel-powered, to maintain consistent pressure and productivity.
