What is CFM and How Many CFM Should My Air Compressor Have?

Kaeser portable air compressor on jobsiteMost construction projects rely on air compressors to power their job-sites and equipment. They power a wide range of tools like pneumatic hammers, rock drills and concrete power cutting saws. A truck can't pull a load without adequate horsepower just like your air compressor can't power your pneumatic equipment if it doesn't generate enough CFM.
What is CFM?

CFM (Cubic Feet per Minute) is the measurement used to describe how much air your compressor releases every minute.

Industrial air compressors use a diesel engine to draw in air, compress it, and release it in a powerful flow. Air is pulled into a chamber and compressed by two rotary screws and then released from a nozzle at the other end. This air can be used to power several pneumatic machines at once including paving breakers, chipping hammers, clay diggers, rivet busters, sand blasters and rock splitters.

CFM vs PSI

PSI (pounds per square inch) is another important measurement for air flow but shouldn’t be confused with CFM. PSI refers to the force of the air your machine can put out (measured in pounds). CFM on the other hand refers to the total volume of the air your compressor can release (measured in square feet). For example, if you were to blow air onto a piece of paper, the PSI would be the pressure on the paper and the CFM would be the volume of the air you were blowing out.

With pneumatic machines, the higher the PSI the harder your attachment will drive. The greater the CFM, the faster it will work. For example, your pneumatic nail gun might be able to deliver nails at 100 PSI of force, but if your CFM is to low, it might only build up enough force to deliver one nail a minute. Alternatively, an adequate CFM will allow you to deliver a nail at 100 PSI every second.

How Many CFM Do I Need?

Most air compressors come with outputs of 185 CFM but they can range all the way up to thousands of CFM. Attachments will generally come with information on their CFM requirements. Breakers can range from 49 to 91 CFM, spikes are around 73 CFM, rock drills can be anywhere from 46.6 to 129 CFM, and chipping hammers generally won’t exceed 32 CFM.

If you only use one tool at a time your compressor should generate enough CFM for your tool with the highest CFM requirements.

If you plan to use more than one tool at a time, your compressor should be able to provide the total CFM of all machines in use. For example, if you plan to use a 55 CFM spike and a 100 CFM rock drill simultaneously, your compressor should have an output of at least 155 CFM.

Forklift Safety Checklist - Working Safely with your Forklift Rental

Forklift Safety Checklist: Don't Rent a Forklift Until You Read This


1. Choose the right forklift for your job and make sure it functions properly



Forklifts come in a variety of size, power, and fuel options. The following guidelines will help you choose the forklift rental that is right for your project, while keeping you safe on the job.

Standard tires are sufficient for indoor work while outdoor jobs may require rough-terrain or pneumatic tires. The forklift's fuel source and engine type are also extremely important. Internal combustion engines offer more power but are not suitable for indoor operation or in poorly ventilated areas. When working indoors, you should stick to LPG (propane) or electric powered forklifts.

Forklift manufacturers affix a “Load Capacity Plate” to each machine. This plate shows the maximum weight or “rated capacity” your forklift can safely lift. Forklift operators should be familiar with their rental forklift's “rated capacity”.

Always confirm that all safety features are fully functional. Make sure the overhead Falling Object Protective Structure (FOPS) protecting the driver is intact, seat-belts are functional and a proper speed control device is fitted to your forklift. The horn, back-up alarm, proximity indicator, and lights should regularly be checked to ensure they are fully functional.

2. Make sure your job-site is forklift friendly



One of the main causes of forklift-related injuries are collisions with people. Forklift operators should take the following steps prior to the start of each new project.

Designate operating zones that are separate from pedestrian zones. These operating zones should be cordoned off with high-visibility barriers. Walkways should be provided to allow pedestrian traffic through work areas. Traffic management plans should be put into place to prevent collisions by separating machines by time or space. These plans should be indicated with signage placed in centralized areas. Employees should be made aware of these zones/walkways and should be updated to changes as they occur. Signs and mirrors should be installed at all blind spots. Hazards such as docks or ramp edges should be clearly marked.
3. Ensure ALL operators are properly trained



Forklift operators should have certified forklift training (call 1-800-DURANTE) or be within the sight lines of a certified supervisor. Operators should be aware of the layout and paths in their “operating zone”. They should always wear seat belts and be aware of hazard signs. Operators should also be mindful of speed limits and should report any damage or incidents while on duty.
4. Keep your forklifts in good working order with proper maintenance



All forklifts in your fleet should be regularly maintained, inspected, and cleaned. Any issues should be recorded and repaired. Pre-operational checklists should be filled out at the beginning of each day. These checklists should be tailored to fit the brand of your forklift and your project’s needs. Forklifts in need of service or repair should be immediately removed from the jobs-site until the necessary repairs can be made.
5. Work smarter not faster


Now that you have the right forklift, your job-site is “forklift friendly”, your operators are trained, and your forklift is in good  working order -  it's time to get to work.

To ensure all safety procedures are followed, operators should be supervised at all times. Hazards like ramps, ledges, or drains, may unbalance your forklift. These hazards should be well marked and avoided at all costs. Managers should allow enough time for operators to complete their projects at safe speeds. Work smarter, not faster.

When loading, unloading, and travelling, all loads should be checked for stability. Operators should be mindful of their forklift's weight limits and should never exceed these capacities. Travel with loads should only be attempted when the forks are down. Finally, procedures for recharging and refueling your forklift should be followed.

These are just a few safety tips to keep in mind when operating your forklift rental at maximum safety levels. For questions, or to inquire which type of forklift rental your job requires, call 1-800-DURANTE or check our our forklift rental website.

What Type of Boom Lift Should I Rent? Straight Boom or Articulated Boom?

Straight boom lifts and articulated boom lifts may look similar, but each serves a slightly different purpose. Use this guide to decide which type of boom lift fits your project's requirements.

Straight Booms

Straight booms are also commonly referred to as “stick booms” or “telescopic booms”. Straight booms usually outperform articulating booms in both reach and capacity. The straight boom's single arm can extend anywhere from 45 to 180 feet, maneuvering maximum capacities of 500 to 1,000 pounds, usually a maximum of two operators. Some straight booms come equipped with "dual-fuel" (gas or LPG) options, for both indoor and outdoor applications as LPG will not create any hazardous fumes.

Straight booms are ideal for situations where horizontal reach is as important as vertical reach. They can extend over rivers, obstacles, and delicate or hazardous areas.These booms have a variety of uses including, sporting events, inspections, bridgework, construction, painting and general high-reach maintenance applications.

Articulated Booms

.
These versatile machines are also known as “cherry pickers”, “knuckle booms” and “up-and-over booms”. They support a work platform at the end of a long boom with several joints or “knuckles” which “articulate”, giving operators a tremendous amount of control. Articulating booms can stretch anywhere from 40 to 141 feet, allowing operators to maneuver up to 500 pounds of  materials, workers, and equipment into hard-to-reach areas. These lifts handle rough terrain conditions better then straight booms. Many feature full-time positive drive traction systems and active oscillating axles for better traction and for situations with varying gradients. Many articulated boom lifts also feature high ground clearance and four wheel drive options.

These machines are ideal for outdoor construction, industrial applications, electrical work, painting, demolition, and certain event applications.


If you have any questions about which type of lift is right for your job or for any general equipment inquiries, call Durante Rentals at 1-800-DURANTE or chat with us live at DuranteRentals.com.
