Six Steps to Optimizing Compressed Air: Step 4, Turn it Off When Not in Use

Step 4 of the Six Steps to Optimizing your compressed air is to turn off your compressed air when it is not in use. This step can be done using two simple methods either by using manual controls such as ball valves or automated controllers such as solenoid valves. Manual controls are designed for long use and when switching on and off are infrequent. Ball Valves are one of the most commonly used manual shut offs for compressed air and other fluids.

Automated controllers allow your air flow to be tied into a system or process and turn on or off when conditions have been met. Solenoid valves are the most commonly used automated control device as they operate by using an electric current to open and close the valve mechanism within. Solenoid valves are some of the more versatile flow control devices due to the fact that they open and close almost instantaneously. Solenoid valves can be used as manual controls as well by wiring them to a switch or using simple programming on a PLC to turn the valve on or off using a button.

Some good examples of automated controllers are EXAIR’s Electronic Flow Controller (a.k.a. EFC) and EXAIR’s Thermostat controlled Cabinet Coolers.  

The EFC system uses a photo eye to detect when an object is coming down the line and will turn on the air for a set amount of time of the users choosing. This can be used to control the airflow for all of EXAIR’s products. EXAIR’s Thermostat controlled Cabinet Coolers are used to control the internal temperature of a control cabinet or other enclosures. This is done by detecting the internal temperature of your cabinet and when it has exceeded a temperature which could damage electrical components it will open the valve until a safe temperature has been reached, then turn off.    

By turning off your compressed air, whether it be with manual or automated controllers, a company can minimize wasted compressed air and extend the longevity of the air compressor that is used to supply the plants air. The longevity of the air compressor is increased due to reduced run time since it does not need to keep up with the constant use of compressed air. Other benefits include less use of compressed air and recouped cost of compressed air.

OSHA Safety Standards for Compressed Air

Safety should always be a serious concern within industrial environments.  Walk through any production facility and you should see all kinds of steps taken to give a safe workplace to the operators, contractors, and other team members.  Whether this is through a sign showing PPE required to enter an area, an emergency exit sign, a safe walkway, or machine guards.  Safety has become a standard that should never be lowered and there is good reason for that.

EXAIR designs all of our products to be safe and they meet or exceed OSHA standards that are directed toward compressed air safety.  The first is to ensure that an operator or maintenance worker will not be injured through air impinging their skin should they come into contact with an EXAIR product.   This OSHA standard is 29 CFR1910.242(b) claiming that all point of use compressed air products must be regulated to have less than 30 psig of dead end pressure.   This directive is critical for worker safety and the way many blowoffs skirt by is to cross drill holes in the end of the blowoff.

Cross drilled holes may satisfy the dead end pressure standard but it does not address OSHA’s next important compressed air standard about noise exposure, OSHA standard 29CFR1910.95(a).  The allowable noise level standard combined with 30 psig dead end pressure will render many home made or retail nozzles near useless because few, if any, meet both standards.  Again, EXAIR has engineered and designed our Super Air Nozzles to permit 80 psig inlet pressure and still meet or exceed both of these OSHA standards so that the work can still be done by the operators while remaining safe and retaining their hearing.

For a better explanation and demonstration of how our nozzles meet these standards please see the video below.

While I use nozzles and cross drilled pipes as examples within this blog these safety features are designed into every product that EXAIR offers.  This is due to the fact that OSHA, NIOSH, and the CDC do not delineate between a blow gun, blow off within a machine, or even a Cabinet Cooler System.  If the device is powered by compressed air then the two key OSHA standard are in effect due to the inherit dangers of compressed air.

I encourage you now to walk through your facility and try to listen or spot compressed air points of use within your facility.  Then, I ask you to call, chat, e-mail, or tweet an Application Engineer here at EXAIR and let us help you determine the most efficient and safest product to get the work done.
