class=\"sm-post\">\n\n  <p class=\"sm-lead\">\n    On most quarry and mine sites, the compressor is the biggest energy user on the drilling line, and a large share of what it produces never reaches a drill. It escapes through worn couplings, cut hoses, open drains and loose fittings. The US Department of Energy notes that leaks often waste 20\u201330 % of a compressor&#8217;s output. That is fuel or electricity paid for, emissions released and drilling pressure lost, every shift. This guide shows how much air a single leak wastes, where leaks hide on a drilling site, how to measure your own leak rate and how to bring it down.\n  <\/p>\n\n  <div class=\"sm-stats\">\n    <div class=\"sm-stat\"><div class=\"sm-stat-val\">20\u201330 %<\/div><div class=\"sm-stat-label\">of compressor output often lost to leaks in poorly maintained systems [1]<\/div><\/div>\n    <div class=\"sm-stat\"><div class=\"sm-stat-val\">&lt; 10 %<\/div><div class=\"sm-stat-label\">leak rate a well-run leak programme can reach [2]<\/div><\/div>\n    <div class=\"sm-stat\"><div class=\"sm-stat-val\">1.7 m\u00b3\/min<\/div><div class=\"sm-stat-label\">lost through one 6 mm leak at 7 bar: more than a Y20 rock drill uses<\/div><\/div>\n  <\/div>\n\n  <div class=\"sm-takeaways\">\n    <div class=\"sm-tk-title\">Key Takeaways<\/div>\n    <ul>\n      <li>A single <strong>6 mm (1\/4&#8243;) leak<\/strong> at about 7 bar can waste roughly 1.7 m\u00b3\/min of air and 11 kW of compressor power, continuously.<\/li>\n      <li>Leaks also <strong>lower the pressure at the drill<\/strong>.

On a quarry or mine site it does two kinds of damage at once.\n  <\/p>\n\n  <div class=\"sm-factor\">\n    <div class=\"sm-factor-num\">1<\/div>\n    <div class=\"sm-factor-body\">\n      <h3>It burns fuel or electricity for nothing<\/h3>\n      <p>The compressor runs longer and more often to replace the air that escapes. On remote sites that air is usually made by a diesel compressor, so every leak shows up in the fuel bill and in the site&#8217;s emissions. Leaks also push operators to add compressor capacity they would not otherwise need [2].<\/p>\n    <\/div>\n  <\/div>\n\n  <div class=\"sm-factor\">\n    <div class=\"sm-factor-num\">2<\/div>\n    <div class=\"sm-factor-body\">\n      <h3>It takes pressure away from the drills<\/h3>\n      <p>Pneumatic rock drills such as the <a href=\"https:\/\/setmakina.com\/en\/products\/tiger-y24\/\">Y24<\/a> and <a href=\"https:\/\/setmakina.com\/en\/products\/tiger-yt28\/\">YT28<\/a> are rated at 6 bar. Leaks cause a drop in system pressure, which makes air tools work less efficiently [2]. For a rock drill that means weaker blows, slower penetration and a higher cost per metre drilled. The common reaction, turning up the compressor pressure, makes it worse: a leak loses more air at higher pressure.<\/p>\n    <\/div>\n  <\/div>\n\n  <h2><span class=\"sm-num\">02<\/span>How much air one leak wastes<\/h2>\n\n  <p>\n    The table converts the US Department of Energy leak rates into metric units and compares them with the air consumption of Set Makina rock drills.

Run one of these tests at a break, when every drill is stopped but the air line is still connected and pressurised [2].\n  <\/p>\n\n  <h3>Method 1: load\/unload time (start\/stop or load\/unload compressors)<\/h3>\n  <p>With no air being used, the compressor still cycles to replace the leaks. Time how long it runs on load (T) and how long it stays off load (t) over several cycles.<\/p>\n  <div class=\"sm-formula\">Leakage (%) = T \u00d7 100 \/ (T + t)<\/div>\n  <p><strong>Example:<\/strong> the compressor loads for 20 seconds and unloads for 80 seconds. Leakage = 20 \u00d7 100 \/ 100 = <strong>20 %<\/strong> of its capacity. That is a typical figure for a system with no leak programme.<\/p>\n\n  <h3>Method 2: pressure decay (any compressor)<\/h3>\n  <p>Bring the system to working pressure, stop the compressor and time how long the pressure takes to fall to about half. You need the volume of the receiver and lines (V).<\/p>\n  <div class=\"sm-formula\">Leakage (m\u00b3\/min of free air) = V \u00d7 (P1 \u2212 P2) \/ (T \u00d7 1.013) \u00d7 1.25<\/div>\n  <p>V in m\u00b3, P1 and P2 in bar gauge, T in minutes. The factor 1.25 corrects for the leak rate at full working pressure. <strong>Example:<\/strong> 1.5 m\u00b3 of receiver and hose volume, pressure falling from 7 to 3.5 bar in 5 minutes: 1.5 \u00d7 3.5 \/ (5 \u00d7 1.013) \u00d7 1.25 \u2248 <strong>1.3 m\u00b3\/min<\/strong>, which is the whole air consumption of a Y20 rock drill.<\/p>\n\n  <div class=\"sm-callout\">\n    <p><strong>Rule of thumb:<\/strong> if leakage is above 10 % of your compressor&#8217;s capacity, the system can be improved [2].

Cutting leaks from 25 % to under 10 % of output means the same drilling work is done with less energy, fewer emissions and often a smaller compressor class. It needs no new machine, and the savings start the day the leaks are fixed. For buyers and contractors who are asked to show what they do to reduce their environmental footprint, a documented leak programme is a simple, measurable answer.\n  <\/p>\n\n  <h2><span class=\"sm-num\">07<\/span>Frequently asked questions<\/h2>\n\n  <div class=\"sm-faq\">\n    <div class=\"sm-faq-item\">\n      <h3>How much compressed air do leaks waste?<\/h3>\n      <p>In poorly maintained systems, leaks often waste 20\u201330 % of a compressor&#8217;s output. A well-run leak programme can bring this below 10 %.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>How much air does a 6 mm leak lose?<\/h3>\n      <p>At about 7 bar, a sharp-edged 6 mm (1\/4&#8243;) hole loses roughly 1.7 m\u00b3\/min (about 62 cfm). That is more air than a Y20 hand-held rock drill uses, and it wastes about 11 kW of compressor power.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>How do I find air leaks on a noisy site?<\/h3>\n      <p>Test during a break when the drills are stopped but the line is pressurised. Listen along the line, brush soapy water on fittings and couplings, or use an ultrasonic leak detector, which picks up leaks you cannot hear.<\/p>\n    <\/div>\n    <div class=\"sm-faq-item\">\n      <h3>Do leaks affect rock drill performance?<\/h3>\n      <p>Yes.
