Shop presses are essential components in many industrial settings, operating by pressurized liquids (usually oil).

Air hydraulic presses are cheaper and require less maintenance than their full-hydraulic counterparts.

These simple machines don't need to be plugged in - instead, muscle power pumps a handle on the jack to cause oil to flow upward and pushes it out through a ram, before retracting downward again.


A pneumatic press uses compressed air (or gas) to generate force to push down on a ram, controlled by applying air pressure through a valve. An air hydraulic press, also known as hydro pneumatic presses, offers a cleaner and quieter alternative than conventional hydraulic presses while still offering strength and power similar to their hydraulic counterparts; furthermore it's 50% more energy efficient requiring up to 50% less power consumption!

Hydraulic Presses

A hydraulic shop press is an iconic choice of rosin press. Reliable and strong, these strong presses make an excellent addition to many jobs involving pressurized materials or large volumes of pressing. However, hydraulic presses tend to take more time in performing their task compared with pneumatic ones, as well as more maintenance than their pneumatic counterparts requiring devices for monitoring oil pressure and efficiency.

Pneumatic presses, however, can generate the same strength more rapidly due to not relying on hydraulic fluid movement for power production; rather they use electrical motors to pressurize air inside their system. Furthermore, these air-powered units are smaller and lighter than their hydraulic counterparts.

These presses are great for tight spaces in an extraction room or for users who prefer an easy and straightforward experience, with less maintenance requirements compared to hydraulic presses as they lack complex internal hydraulic systems which could break down over time.

Although pneumatic rosin presses do not offer as much control as hydraulic presses, they still can perform similar tasks. For instance, adding an indexing table to an air hydraulic press makes working on larger pieces easier; this feature is especially helpful for extractors using pre-made rosin.

A 20 Ton Air Hydraulic Shop Press can be fitted with a rotary indexing table so users can smoothly move its ram up and down simultaneously, and is compatible with premium rosin plates from The Press Club.


Air hydraulic presses tend to be smaller than their hydropneumatic and hydraulic counterparts due to relying on potential energy from compressed air instead of fluids as their source of potential energy. Furthermore, the size of cylinder housing piston that generates force also plays an integral role. Therefore it's vital that you consider Platen PSI (Pressure at Rosin Bag During Extraction) when selecting your press.

Pneumatic presses tend to be less costly than hydraulic presses because they don't require power outlets or pumps for operation, saving on energy costs. Plus, pneumatic presses offer greater precision pressure control, with extractors dialing in exact pressure levels needed to produce higher quality rosin extract.

Hydraulic presses boast greater tonnage capacities than pneumatic presses, and often feature heavy-duty H-frame construction with internal pressure gauges attached to their ram cylinder for monitoring force as well as seeing how much pressure you are applying to Rosin Press Plates with your press handle.

Hydraulic presses can also be easily customized, as they come equipped with an assortment of Rosin Press Plate sizes and types to meet a range of customization needs. Furthermore, many models feature an adjustable table - perfect for metalworkers such as fabricators or welders who must shape large sheets of steel in an efficient manner.

How they work is straightforward. By pumping a handle on a jack with muscle power, oil from its reservoir is transferred into its main (much larger) cylinder which pushes upward against the base of its ram and forces it down onto your workpiece. A valve at the bottom of its ram cylinder then allows pressure to release, and allows its return down toward the workpiece.

Therefore, those looking to maximize force output while reducing size and cost should opt for a double-acting hydraulic press. While more costly than pneumatic or hydropneumatic presses, they provide significantly more power and functionality than their simpler counterparts.


Hydraulic presses utilize fluid mechanics to generate force, using a piston that presses down into a liquid-filled storage tank and transmitting its internal pressure via the cylinder to the top plate of the machine. A pressure gauge attached to the cylinder indicates how much force can be exerted from each press; its force output can also be read off on an attached pressure gauge located near its front. As they don't require electricity for operation, hydraulic presses tend to have simpler designs compared with electric models; additionally they feature H-frame constructions which utilize as little bulk while still creating adequate force output while still performing their task effectively.

Air over hydraulic presses are a distinct kind of hydraulic press that combines the advantages of pneumatic and hydraulic systems, operating initially using only compressed air but activating their hydraulic power stroke when resistance arises. As such, they require reduced maintenance costs and can save up to 50% in energy usage when compared with fully hydraulic or pneumatic systems.

Quieter hydraulic machines also prove advantageous for worker safety and production output, meaning loud noises won't disrupt your team and keep them from focusing on their task at hand. Furthermore, having no excess noise makes it easier to identify problems within equipment or work that requires attention more easily.

Pneumatic presses are easier to maintain than hydraulic ones because they don't rely on complex fluid systems like hydraulic oil for operation; instead they feature simple seals and pneumatic components that can be repaired or replaced easily without extensive disassembly of the entire machine. Furthermore, with less parts, pneumatic presses tend to be cheaper to operate and maintain than their hydraulic counterparts that produce forceful forces.

Some hydraulic presses are employed for industrial purposes, including scrap baling presses that crush cars and equipment to recycle their raw materials, while powder compacting presses compact powdered material into various shapes, designs, and densities.


An air over hydraulic press offers an affordable alternative to traditional hydraulic presses. Utilizing compressed air as power and hydraulic oil as the means for movement of its ram, an air over hydraulic press relies on compressed air for power while hydraulic oil moves the ram instead of piston and cylinder configuration like its mechanical counterparts do. As a result, they're significantly easier and less costly to maintain compared with fully hydraulic alternatives - with fewer moving parts that need to be lubricated regularly by pressurized oil, leading to less breakdowns as well as lower repair costs overall.

As with any piece of equipment in your shop, air hydraulic presses require regular inspection and maintenance in order to remain safe for use. Failure to address issues promptly could lead to their collapse and result in injury or even death for those using them; for this reason it's imperative that machinists follow strict safety protocols when operating these presses and ensure all necessary components are in working condition before commencing operation.

Planning is essential to getting the most from your press. That means knowing its capacity, power and requirements for your specific project. For instance, larger bed areas might be beneficial when doing large projects; you'll also want to consider its maximum stroke length as some machines offer shorter strokes while others provide longer ones.

Though hydraulic presses are generally safe and reliable machines, like all machines they can pose a danger if used incorrectly. Therefore, it's imperative that workers who use one receive adequate training and education prior to operating it safely. Furthermore, investing in high-quality safety equipment like ejection curtains and anti-restart motor control units would also be wise as well as considering adding locking devices on your press.

There are various kinds of air hydraulic presses, such as H frame, C frame and 4-post presses. While each has their own set of advantages and drawbacks, their basic designs remain similar across them all - featuring frames with tables or bolsters where your item sits as well as rams - this makes finding one to suit any project from a simple sheet metal job to something more complex straightforward.
