Section A INTRODUCTION The purpose of this manual is instruction on the proper assembly and care of Solberg inlet air filters. *WARNING* This manual must be read and thoroughly understood before using and caring for this air filter. Failure to comply could result in explosion, product/system contamination or personal injury. This manual should be used as a supplement to the user’s understanding of the proper care needed to maintain a safe and dependable LRS unit.
No. Model Number Replacement Element Initial Delta P Readings 1 2 3 4 5 Table 1 The model number designates the filter type, the original element configuration and housing connection size. For example, the following part number identifies the filter as being a ‘LRS’ design filter with a 237 element and 2” FPT half coupling connection size: LRS-237-200HC Filter Type: LRS Element Type: Size, Material, Prefilter, Micron Rating Connection Size and Type 2.
Rule of Thumb #1: Always begin with the filter cartridge requirements when sizing a filter. Once the appropriate element has been selected, move on to the housing requirements. Rule of Thumb #2: Always ask or specify a filter based on a micron rating with filtration efficiencies. As an example, stating a requirement for a 1-micron filter is misleading because no efficiency rating has been specified. A 1-micron filter at 95% efficiency may be less efficient than a 5-micron filter at 99% efficiency.
Rule of Thumb #4: Pressure drop is also caused by the dirt holding capacity of the element. As the element fills up with dirt, the pressure drop increases. It is important to document the pressure drop across a given filter when it is new and then clean or replace it when the pressure drop increases by 10” to 15” / 250280mm H2O over the original reading. Rule of Thumb #5: The inlet connection greatly influences the overall pressure drop of the filter system.
4. Element Cleaning - Inlet Filtration Solberg elements should be cleaned or replaced, once the pressure drop reaches 15 to 20-inches water column (380 - 500mm WC) above the initial pressure drop of the installation. The decision to clean the element rather than replace it is left to the discretion of the operator. Any damage which results from by-pass or additional pressure drop created by element cleaning is the sole responsibility of the operator.
C. Polyurethane Prefilter: The prefilter may be washed as a sponge or replaced to give the element a longer service life. D. Epoxy Coated Wire Mesh and Stainless Steel Wire Mesh Elements: Cleaning instructions similar to polyester, except mild solvents may be used. E. Activated Carbon Element: Not cleanable F. Polypropylene Element: Cleaning instructions similar to polyester G.
A. Maximum operating temperature for most Solberg inlet air filter products is 220°F / 105°C. Temperatures in excess of this could cause damage to elements, media and elastomers. High temperature products are available. B. Direction of flow is typically from the outside of the element to the inside of the element. Most products have arrows indicating direction of flow on the inlet and outlet ports. C. Ensure that pipe connections are adequately sealed so the potential for leaks is reduced to a minimum. 2.
3. Removing Element for Service/Maintenance. A. Remove retaining hex head/wing-nut and washer carefully, and then remove element. B. Clean sealing surfaces of housing and element endcaps so that they are free of dirt or any other particulate. Figure C.3.1: Retaining washer and wing-nut. Figure C.3.2: Element removal. Figure C.3.3: Element free from housing. Page 10 Solberg Manufacturing, Inc., 1151 Ardmore Itasca, IL 60143 USA Ph: 630.773.1363 Fax: 630.773.0727 Email: sales@solbergmfg.com Web: www.
*WARNING* Failure to comply with these instructions may result in system or equipment contamination. 4. Securing Element. A. Place new or cleaned element evenly on base plate by inserting threaded bolt through bolt hole on the element end cap. Be sure the element seats properly in the housing top and there is no dirt or particulate present on sealing surfaces. B. Secure element with washer and wing nut to end cap and bolt. Element must be tightly secured. Note: DO NOT over tighten! Figure C.4.
5. Securing Canister Top to Canister Base. A. Make sure all surfaces are free from dust and other particulate. B. Hemisphere O-ring must rest evenly along canister base O-ring groove, see figure C.5.1. C. Secure V-band by disconnecting hex nut or T-bolt portion and placing Vband along the diameter of canister O-ring groove. Fasten nut or Thandle and secure tightly. V-BAND LEGS MUST REST UNIFORMLY ALONG ENTIRE O-RING GROOVE! See figures C.5.2 and C.5.3. Figure C.5.
6. Equipment Startup. A. Be sure to read the instructions on installation or element replacement as listed above before starting equipment. *WARNING* If at any time the operator is unable to verify the integrity of the element or any housing feature, the factory or a regional representative should be contacted prior to start-up. B. Please check the listed steps prior to startup. 1. Check element to make sure it is seated properly in housing top.
Section D MAINTENANCE RECOMMENDATIONS 1. Pressure drop readings are recommended to have an effective air filter. Always document initial pressure drop during start-up when element is clean. Replacement cartridge is needed when system experiences 10” to 15” / 250380mm H2O above drop above the initial reading. Refer to page 4 for initial values. 2. Always check replacement cartridge gaskets to insure they are adhered uniformly along the end caps during handling. If not, contact Solberg Manufacturing, Inc.
