Swift Equipment Solutions Air Compressor Buying Guide

Air compressors, today, are worksite staples. A variety of industries conduct day-to-day operations via air-powered tools, and an air compressor’s electrical freedom is highly sought after by decision makers. Many don’t require a motor for use, and temporary sites—like festival and fairgrounds—benefit greatly from their pick-up-and-go design.

Serving uses in individual toolkits and industrial production sets alike, air compressors are useful for powering paint sprayers, finish nailers and impact wrenches. Power and versatility are an air compressor’s chief benefits, but every product contains a slew of options for diverse projects. Regardless of your project’s scope, location or requirements, an air compressor can accommodate for most tasks.

When selecting an air compressor, however, you should take the following considerations. Follow this guide below, and select the perfect air compressor to meet your workplace’s needs.

Select the Right Type

Air compressors are available in three types. While each is useful, each offers features specific to different work needs.

Reciprocating Air Compressor

A reciprocating air compressor uses positive displacement to boost air pressure. By limiting air volume, a reciprocating air compressor creates between one and 15 hp. These air compressors are available in one-stage and two-stage versions.

Rotary Screw Air Compressor

A rotary screw air compressor is a positive displacement compressor offering continuous duty via interior cooling. Rotary screw air compressors, because of their high sustainability, don’t need external cooling. Internal parts are always spared from extreme operating temperatures, granting them access to outputs between 7.5 and 100 hp.

Centrifugal Air Compressor

Centrifugal compressors don’t require positive displacement to operate. A high-powered option, the centrifugal compressor maintains a constant output above 100 hp. Worksites requiring continuous demand benefit greatly from centrifugal air compressors.

Additional Options

While air compressor type refers to a worksite’s direct workflow needs, additional options are available for decision makers needing diverse solutions and flexible services. Air compressors are available in different designs, spanning across size, weight and portability. Once you’ve selected the perfect compressor to meet your project’s needs, consider the following options.

Portable Design

Portable air compressors are easy to transport. They’re lightweight, and they can be mounted on industrial carriages pulled upon two to four wheels. A portable air compressor, capable of being taken anywhere, powers air tools across many work environments. A portable unit doesn’t need an extra-long hose, and it is often a reciprocating unit requiring less power. Compared to its larger counterparts, a portable air compressor requires significantly less resources to run.

Stationery Design

Stationary air compressors, while unmovable, offer significantly more power than portable units. Crafted to serve long-term projects, a stationary air compressor offers incredibly CFMs. They do, however, require a particular installation. Often, the operator must drill a stationary unit’s hose through a wall, mounting it above the work area. High-end rotary screw compressors are often stationary units.

Towable Design

Towable compressors, meanwhile, are often located on jobsites or in forestry projects. Towable units, mounted atop trailers, are paired with steel chassis and galvanized canopies to complete heavy duty projects. Often bound by a simple connection, such as a lifting eye hitch, towable air compressors can be equipped to any sizable work vehicle. Typically, towable compressors create between 14 and 327 hp.

Truck Mounted Design

Truck mounted air compressors are incredibly similar to stationary air compressors. Unlike stationary units, however, they can be transported between job locations without requiring disassembly or reassembly. Large, truck mounted units can power several air tools simultaneously. Environmentally-friendly, many truck mounted units are fully run via electricity. Frequently, these all-electric options grant users cost freedom from lack of fuel needs. Similar to a stationary model, a truck mounted air compressor requires hose access by running equipped hoses from the host truck to the work area.

Air Compressor Specification

When selecting an air compressor, you should consider several specifications. Air compressor operation is governed by a few factors, determining the unit’s usability, value and flexibility. When comparing different models, consider the following:

Stages

An air compressor’s “stages” are its number of contained cylinders. When selecting an air compressor, you have two options:

Single Stage

Single stage compressors contain a singular cylinder. Often, they can reach a maximum of 120 psi. Normally used for small shops and households, single stage air compressors are both lightweight and portable.

Multistage

Multistage compressors are constructed to handle multiple pneumatic tools requiring over 120 psi. Harnessing over one cylinder, multistage compressors compress air within an initial cylinder before transferring air into alternative cylinders. Doing so achieves higher power levels, granting higher psi. Multistage compressors do, however, require a cooling component.

Power Source

An air compressor’s power source (diesel driven air compressor engine, gas, electricity) determines its functionality in different areas. A unit can be powered by either gas, diesel or electricity, giving operators different options on a worksite-to-worksite basis. Output is, however, impacted by power source. In general, air compressors are available in three power options:

Gas Driven Air Compressor Engines

Gas-powered air compressors are often portable. They’re a solid alternative in rural areas and worksites not connected to a power grid. Unfortunately, gas-powered units can weigh over 2,000 pounds. While incredibly powerful, gas-powered units generate a lot of noise.

Diesel Driven Air Compressor Engine

Diesel-powered air compressors offer a higher output than gas-powered units, generating between 185 and 1,600 CFM. Typically, a diesel-powered air compressor needs to be mounted or towed. Diesel driven air compressors are, however, incredibly versatile. For this reason, they’re an optimum choice for projects requiring a wide range of tool connections.

Electricity

Electric-powered air compressors are incredibly common. Often lightweight and compact, electric models are ideal for enclosed-space projects. Requiring a standard wall socket for operation, electric models are highly viable for residential projects. That said, units producing higher CFMs may require higher voltage from a larger power source.

Used Rotary Screw Air Compressors: Look for Them Online


The rotary screw air compressors are a type of gas compressors used to provide a high-pressure air output for industrial applications. These equipment use male and female helical screw (called rotor) combinations to compress the gas. The output effectiveness depends on the fitting between the different rotors and between these rotors and the chamber.

There are various reasons why these compressors are so popular. For one thing, the leakage in these compressors is quite less resulting in better efficiency. Though a certain amount of leakage does occur in these rotary screw equipment as well, the high rotational speed is usually able to combat any decrease in the air pressure. Secondly, you get a steady flow of air even at high volume. These compressors also come in variable speed options that reduce energy use and thus, the cost.

These equipment are quite popular and even used rotary screw air compressors find takers in the market. There are various companies that sell them online after the necessary refurbishments. These used yet renovated machines are quite popular and most industries, factories and industrial / construction sites prefer to buy these machines at a much lesser cost than the original ones.
If you are looking for these machines and thinking about checking out the used compressors market online, then here are a few things to keep in mind:

The company has manufacturing facilities in the United States, China, and India. It is an ISO 9001 certified company with has high standards in delivering quality and reliability in manufacturing. Sullair has been a leading name in air compressors for more than 50 years and first to execute successfully the rotary screw technology in their compressors.

Sullair 185 is a type of portable rotary screw compressor. They are more efficient and perform better than traditional piston type compressors where high volume with a steady flow is required. These portable air compressors are often used for all-weather medium and small scale industrial applications. One of the most common uses is for powering high-power pneumatic tools.
The Sullair 185 air compressor works based on a continuous rotary sweeping motion. This enables the unit to perform with almost no pulsation or flow surge. It uses two mechanical helical screws, also known as rotors, to compress the gas. It features an oil flooded system with an integrated leak-free design.

From a layman’s perspective, the air is compressed as it passes between the threads of the helical screws. The actual science behind the compression is much more interesting. It is a combination of principles of fluid mechanics. For the actual user, this means little to nothing, but these are at the heart of the working principle of air compression technology. More specifically, it is the principle of compressible flow or gas dynamics, which is only a subset of fluid mechanics. Compressible flow concerns itself with the changes in fluid density, in effect covering everything from rocket engines to shower heads.

The Sullair 185 air compressor is powered by a turbo-charged tier 4 emission compliant 111 CID Kubota diesel engine that outputs 49 bhp of power at an operating rpm of 2720. It is this engine that allows the Sullair 185 to be as efficient as it is. The rated efficiency is 10.2 gallons per hour when operating at 100% capacity. With all this top tier technology, the Sullair 185 is a true workhorse that will serve you well for several years.
