Pneumatic FRL triple <\/a>unit (filter + regulator + lubricator) is enough. In fact, you might be making a very expensive mistake. Is specifying a high-end air treatment unit just flashy cost waste, or essential help when you need it most? Today, let’s dig into this topic.<\/p>\n\n\n\nCompressed air used in automated equipment has many hidden requirements beyond the familiar ones of pressure and flow. The international standard ISO 8573-1 defines clear quality classes for solid particles, water content, and oil content.<\/p>\n\n\n\n
So, how do you correctly select an air treatment unit? It’s actually quite simple. Take the selection tool from a certain brand as an example \u2014 just choose your application scenario. The tool lists six typical scenarios, each corresponding to different compressed air quality classes. After selecting a scenario, the tool displays the required quality classes and the necessary filtration components.<\/p>\n\n\n\n
\u00b7 For standard pneumatic applications, ISO 8573-1 class 7:4:4 is sufficient; a filter with 40 \u03bcm rating is enough.<\/p>\n\n\n\n
\u00b7 But for food & beverage, optical, or precision electronics applications, class 3:4:1 is required. The key point here is: a precision filter with 0.01 \u03bcm rating alone still cannot meet oil content class 1; an activated carbon filter is necessary.<\/p>\n\n\n\n
If you are focusing on a single critical piece of pneumatic equipment (such as an electric spindle’s air seal, a linear scale’s purge air, or an air bearing), the technical manual for that component will usually specify the required compressed air quality class. Simply enter that class, and the selection tool will automatically list the required filtration components. Obviously, these requirements go far beyond what a standard triple unit can handle. Many people neglect this and simply fit a triple unit, only to end up with hundreds of thousands in equipment damage or production losses \u2014 a regret that comes too late.<\/p>\n\n\n\n
It should be noted that the components selected via the tool above primarily treat solid particles, water, and oil, thereby improving compressed air quality \u2014 this is the “indispensable help” foundation. On top of that, you can add “icing on the cake” \u2014 functional highlights for your equipment.<\/p>\n\n\n\n
Take the following customer, who had very high demands for air source quality because they wanted their equipment to be truly competitive. Let’s look at the seven highlights they achieved:<\/p>\n\n\n\n
1. Quality class zoning for different components \u2014 Within the same machine, pneumatic components with different precision requirements are supplied with different grades of compressed air.<\/p>\n\n\n\n
2. Working pressure zoning for different stations \u2014 Each station can have its own independent working pressure according to process needs, without interference.<\/p>\n\n\n\n
3. Lubricated vs. non\u2011lubricated zoning \u2014 Components requiring lubrication receive oil\u2011mist air, while components that must not contact oil (e.g., sensors, purge air) receive oil\u2011free air.<\/p>\n\n\n\n
4. Automatic on\/off control of air supply \u2014 Remote control (via PLC or host computer) of each branch’s air supply.<\/p>\n\n\n\n
5. Safe emergency stop function \u2014 Rapid exhaust of residual pressure in emergencies to protect personnel and equipment.<\/p>\n\n\n\n
6. Energy consumption monitoring \u2014 Real\u2011time monitoring of compressed air flow and pressure to detect leaks and optimise energy usage.<\/p>\n\n\n\n
7. Sleep energy\u2011saving function \u2014 Automatically reduces or cuts off non\u2011essential air supply during machine standby, significantly reducing compressed air system energy consumption.<\/p>\n\n\n\n
Faced with such a premium configuration, consider these questions:<\/p>\n\n\n\n
\u00b7 If you are an equipment user: Would you want your equipment to have these functions? Do you recognise the long\u2011term benefits they bring \u2014 lower failure rates, less downtime, safer and more convenient operation, and transparent energy management?<\/p>\n\n\n\n
\u00b7 If you are an equipment manufacturer: Do these highlights help you win orders (especially from high\u2011end customers)? Do they help you increase your selling price (differentiating from low\u2011price competitors)? Do they help you reduce after\u2011sales service costs (by minimising quality complaints caused by air source problems)?<\/p>\n\n\n\n
If you also want to improve and optimise your air treatment unit, or when discussing proposals with customers \u2014 beyond just price \u2014 have truly impressive technical highlights (especially by upgrading or expanding from a basic triple unit), feel free to contact me. I can assist you in getting this done.<\/p>\n\n\n\n
