{"product_id":"liebert-195531p3","title":"Liebert 195531P3 Filter","description":"\u003cp\u003eWhen you're dealing with high-performance environmental control systems, using the \u003cstrong\u003eLiebert 195531P3 Filter\u003c\/strong\u003e is critical for maintaining design-specified airflow and protecting sensitive downstream components. This \u003cstrong\u003e18 x 24 x 4 MERV 8 air filter\u003c\/strong\u003e is engineered as an exact OEM replacement for Liebert cooling units, ensuring a seamless fit and high-integrity seal within the filter rack. The \u003cstrong\u003epleated media\u003c\/strong\u003e provides increased surface area compared to standard panel filters, resulting in a \u003cstrong\u003elow pressure drop\u003c\/strong\u003e across the coil and optimized thermal management. By capturing airborne contaminants such as dust, pollen, and lint, this \u003cstrong\u003edeep-pleated HVAC filter\u003c\/strong\u003e prevents debris from insulating the evaporator fins, which can lead to inefficient heat exchange or compressor slugging. Contractors rely on the \u003cstrong\u003enominal 18 x 24 x 4 size\u003c\/strong\u003e for consistent performance in data centers and precision cooling environments where maintaining \u003cstrong\u003eindoor air quality\u003c\/strong\u003e is not just a preference, but a technical requirement.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision OEM fit\u003c\/strong\u003e specifically designed for Liebert environmental units, preventing air bypass.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh dust-holding capacity\u003c\/strong\u003e through deep-pleated synthetic media, extending service intervals between maintenance cycles.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized static pressure\u003c\/strong\u003e helps maintain blower motor efficiency and reduces energy consumption across the \u003cstrong\u003eHVAC system\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMoisture-resistant frame\u003c\/strong\u003e construction ensures structural integrity in high-humidity cooling applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the actual size versus the nominal size of this filter?\u003c\/strong\u003e\u003cbr\u003e\nThe nominal size is 18 x 24 x 4 inches. While nominal sizes are industry shorthand, the actual dimensions are slightly smaller to ensure a standard slide-in fit within the \u003cstrong\u003efilter track\u003c\/strong\u003e without binding.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs a MERV 8 rating sufficient for precision cooling zones?\u003c\/strong\u003e\u003cbr\u003e\nYes, \u003cstrong\u003eMERV 8 filtration\u003c\/strong\u003e balancing effective particulate capture with high airflow volume is standard for most industrial Liebert applications. It protects the \u003cstrong\u003ecooling coils\u003c\/strong\u003e from fouling while maintaining the high CFM required for technical spaces.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow often should these filters be inspected in a data center environment?\u003c\/strong\u003e\u003cbr\u003e\nIn high-uptime environments, we recommend a monthly inspection. While the \u003cstrong\u003e18x24x4 air filter\u003c\/strong\u003e is robust, high-volume air movement can lead to faster loading; replacing them when static pressure exceeds site specs is best practice.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
