Portable compressors vary in size and can meet diverse pressure, airflow, and power demands. Knowing the specifications of the tools employed will assist in identifying the necessary compressor size

Airflow is measured in CFM (cubic feet per minute) and generally varies from 35 to 800 CFM for portable models. Pressure is expressed in PSI (pounds per square inch), with industrial portable compressors operating between 100 and 218 PSI. Horsepower (HP) gauges an engine’s size. A higher horsepower indicates greater power, allowing it to operate larger tools or many at once.
The airflow, pressure, and horsepower (Hp) of the compressor are essential specifications for the efficient functioning of your tools and equipment. Insufficient airflow or pressure can lead to compatibility problems and prolong tasks, wasting valuable time on the job site. On the other hand, a compressor that is too large is less efficient and heavier, leading to higher operating costs.
Canada features some of the harshest terrains and weather, yet the work must continue. Portable industrial compressors need to withstand the extreme cold of winter and the heat of summer. They frequently operate in less-than-ideal environments, where dust, pollen, altitude, and humidity can take a toll. Depending on your working environment, look for features such as advanced filtration, moisture control, and solid enclosures to protect from job-site hazards. If you expect to be working in cold temperatures, look for compressors with designed with this in mind, such as cold-weather packages.
In remote areas, reliability is particularly vital due to potential delays in sourcing replacement equipment. Choose a compressor that complies with international standards like UL, ASME, CSA, CRN, and OSHA and comes with a top-tier warranty.
If the compressor is compact, you might load it onto a truck or mount it on a skid for truck installation. Features such as retractable handles and pneumatic tires facilitate movement by a single person. Larger models are intended for towing, necessitating a towing bar. Heavy-duty axles are essential, as road conditions may be harsh. Be sure to verify the vehicle’s towing capacity to ensure it meets the requirements for safely transporting the compressor.
ELGi designs and produces a wide selection of portable air compressors well-suited for industrial applications, including mining, sandblasting, construction, oil and gas separation, cable laying, cleaning, chipping hammers, waterfall drilling, and coal bed methane (CBM). ELGi compressors are renowned for their reliability, efficiency, and low lifecycle costs. The range offers multiple pressure options, features a silent liquid cooling system for the engine, and incorporates a centralized, keyless control panel for effortless monitoring. ELGi’s portable compressors conform to applicable international standards (UL, ASME, CSA, CRN, and OSHA) and comply with emission and noise standards.
ELGi portable compressors come with a 5-year/ Unlimited Hour Airend Warranty.
No, it does not. However after an install, you should power up the system from 0 to whatever the cut-off pressure is and check for any leaks that may be present.
In order to determine what size compressor will meet your requirements you need to establish how it will be used. For example, if you will be using it to power air tools, then you need to determine the CFM of each tool. There are many applications for air compressors. If you need help deciding which size is best for you, please contact Mi‑T‑M at 800-553- and we will be happy to assist you.
Air pressure is determined by the highest minimum pressure requirement. For example, some tools consume more air than others. Tools such as pneumatic nail-guns and staplers consume smaller amounts of air, while air grinders and sprayers consume larger amounts. Most tools have an usage rating for CFM consumption at a recommended PSI. This can be found on the tool itself or in the owner's manual supplied by the tool manufacturer.

The notation CFM (Cubic Feet per Minute) refers to a volume of air produced by the air compressor at a given pressure or PSI (Pound per Square Inch). The right size air compressor will meet your needs in two essential areas: air flow (CFM) and pressure (PSI). It's important to get a compressor that meets your needs in both areas - otherwise you risk damage to both your tools and the compressor itself. Always use CFM and PSI specifications from the nameplate on the product.
On a single stage pump the air is compressed one time and stored in a receiver. A two stage pump compresses the air twice, once in the first cylinder and then a second time in a smaller cylinder which gives you a higher CFM.

A reciprocating compressor is a very flexible piece of equipment but some cautions must be taken for an installation site selection. Refer to the instruction manual that is supplied with each unit. Some things to consider:
No, this is not recommended as the compressor unit must not come in direct contact with the elements. The best practice is to either put a lean-to over the unit or install it in a small building. If installed under a lean-to, we recommend a TEFC motor and NEMA 12 electrical enclosures. Also, when necessary cold weather protection for the oil and other lubricants is recommended.
Yes, the higher air pressure will increase the amount of stored air. At 175 PSIG an 80 gallon tank will store 127 cu. ft. of air. The same 80 gallon tank at 100 PSIG will store only 73 cu. ft. of air.
No, this is not up to the approved code for compressed air systems. The PVC is an oil based product and it does not react properly to heat, vibrations and oil vapor that is carried in the air compressor discharge air. The PVC is prone to bursting under the normal air pressure and unit operations. Consult your local building inspector for piping recommendations.
We recommend using non detergent oils that has been formulated for use in reciprocating compressors. DO NOT USE DETERGENT OILS in the compressor. The detergent oils will foam and cause excessive oil carryover past the piston rings and will not provide the required lubricity for the moving parts.
For a Reciprocating air compressor, generally you would change the oil and the air filter approximately every 3 months. For a more accurate time frame, contact Mi‑T‑M at 800-553- with your air compressor model number and we will help you find the recommended schedule for your compressor.
Starter
The starter is a magnetic device that induces electricity into the motor windings to energize them for work. The starter gets its signal from the pressure switch.
Pressure Switch
It measures the cut in and cut out pressure bands for the compressor start and stop settings and either turns the motor on or off as needed.
After Cooler
An after cooler is a device that uses air flow to cool the compressor discharge air temperature prior to being put into the tank for storage. This cooling function will drop out moisture that is in the compressed air.
