Choosing an Air-Operated Grease Gun

An Air operated grease gun is an air-powered tool that uses compressed air to dispense lubricants. These tools are used in a variety of applications, including car applications and maintenance. Air grease guns have a higher efficiency and are easier to use than manual grease pumps. Taihong carries several different types of air-operated grease guns to meet your needs. Each type of gun has its benefits and drawbacks. Some are ideal for low-volume applications, while others are well suited to high-volume settings.
When selecting an air-powered grease gun, consider the amount of volume you need per stroke. Some guns deliver a single stroke of grease every 3-4 seconds, while others are more powerful and can dispense as much as 29cc per 40 strokes. Additionally, the handle design and weight of the gun also impact its usability. Lever-handle guns are easy to operate but require two hands. Pistol-grip guns offer an ergonomic design and are easier to use in tight spaces.
Other factors to consider when choosing an air grease gun include the maximum pressure a gun can apply and its ease of operation. Some types of air-powered guns generate extreme pressure and can be dangerous to operate if the hose or nozzle isn't properly rated for that level of pressure. Some models have a shut-off valve that helps prevent accidental discharge of excessive grease.
The nozzle of an air-powered grease gun attaches to a hose or pipe extension, which then fits over the grease nipple on zerk fittings. Couplers, which are attached to the end of the hose or extension, snap onto the grease gun head and lock into position, creating a seal-proof passage for the lubricant to flow into the nipple. A metal “straw” or pipe extension can be attached to a hose for additional flexibility, which may be helpful in settings where the zerk fitting is hard to reach.
Another option is a bulk loading grease gun, which is loaded using packaged cartridges that are inserted into the gun's loader valve. This method offers a lower environmental impact than using drums, as the cartridges are not discarded in landfills. Alternatively, barrel pumps can be installed on pails or buckets of bulk grease and connected to the gun's loader coupler. These pumps are more time-consuming to refill than cartridges, but offer a less expensive alternative and allow you to control the exact amount of grease needed for each application.
Considering the various features of each type of grease gun, the best choice is a model that meets your needs and budget. Choose a model that can be operated manually or with a remote controller for easy operation in tight spaces. An air-bleeder feature helps purge air pockets from the nozzle and help avoid grease buildup. For increased durability and performance, choose a model with a heavy-duty die cast gun head, precision-honed internal bore and an automatic air bleeder. An air compressor is required to power these models, so make sure you have one available before purchasing.
