What Factors Affect the Actual Air Displacement of a <a href=\"https:\/\/baldor-air.com\/fr\/compresseur-dair-a-vis-sans-huile-2\/\">Screw Air Compressor<\/a>?<\/h3>\n<\/div>\n<\/div>\n\n\n\n<p>While the <strong>theoretical displacement<\/strong> of a screw compressor depends on the rotor tooth volume, rotor count, and speed, the <strong>actual air output<\/strong> is often lower due to several operational factors:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Key Influences:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Internal Leakage<\/strong><br>Even though rotors in a screw compressor do not contact each other or the casing directly, small gaps lead to gas leakage. Leaks between rotors or from high-pressure zones back to the suction side reduce air output. Worn-out sealing lines, such as sealing teeth or grooves on the rotor tips and ends, can worsen this issue.<\/li>\n\n\n\n<li><strong>Inlet Air Conditions<\/strong><br>As a <strong>positive displacement compressor<\/strong>, the intake volume remains fixed. However, high intake temperature or excessive intake resistance lowers air density, reducing the <strong>mass flow rate<\/strong> of discharged air.<\/li>\n\n\n\n<li><strong>Cooling Efficiency<\/strong><br>Heat generated during compression can cause air expansion before intake is completed. Poor cooling performance\u2014whether due to inefficient <strong>oil cooling<\/strong> ou <strong>water cooling<\/strong>\u2014raises internal temperatures and reduces overall intake volume.<\/li>\n\n\n\n<li><strong>Rotational Speed<\/strong><br>Air displacement is directly proportional to rotor speed. A drop in <strong>motor speed<\/strong>\u2014caused by low voltage or frequency fluctuations\u2014can decrease air output accordingly.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><\/p>\n<\/blockquote>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-1024x768.jpg\" alt=\"compresseur d&#039;air \u00e0 vis\" class=\"wp-image-2620\" srcset=\"https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-1024x768.jpg 1024w, https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-300x225.jpg 300w, https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-768x576.jpg 768w, https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-1536x1152.jpg 1536w, https:\/\/baldor-air.com\/wp-content\/uploads\/2025\/05\/Screw-Air-Compressor-1-2048x1536.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">compresseur d'air \u00e0 vis<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<h3 class=\"wp-block-heading\">2.
