Briggs & Stratton Air Filter 1B20/1B30/BS600 | 75mm H Pleated Cartridge Air Filter for B&S Walk-Behind Lawn Mower Engines
High-Capacity Cylindrical Cellulose Pleat Element with Perforated Metal Outer Sleeve & Gear-Pattern Top Cap
B&S lawn mower 1B20/1B30/27/30/40/50 BS600 1B20V 1B30V Air filter H：75mm
This 75 mm cylindrical air filter is the OEM-spec replacement cartridge for a wide range of Briggs & Stratton 4-stroke walk-behind lawn mower engines. The filter media is a high-density cellulose pleat element - pleated to maximize surface area within the compact 75 mm form factor - enclosed in a perforated metal outer sleeve that protects the pleats from impact, oil splash, and debris while maintaining full airflow. A black plastic gear-pattern top cap provides a secure, indexed mount onto the carburetor intake housing.Lawn mower engines operate in the dirtiest environment of any small engine - a vortex of grass clippings, dust, pollen, and soil particles churned up by the rotating blade directly below the engine deck. A clogged or torn air filter leans out the fuel mixture (more air, same fuel), causing hard starting, power loss, and - over time - scored cylinder walls and piston-ring wear from abrasive dust ingestion.
Technical Profiles & Materials
Pleated Cellulose Element - Maximum Surface Area, Minimum Restriction: The filter media is a resin-impregnated cellulose paper, pleated into a radial accordion pattern and bonded to the black plastic top and base caps. Pleating multiplies the effective filtration area by a factor of 8–10× compared to a flat disk filter of the same diameter - the engine breathes through square inches of media, not a single disk. This keeps airflow restriction low even as dust loads accumulate on the outer pleat surfaces, extending the service interval between filter changes.
Perforated Metal Outer Sleeve - Impact & Debris Protection: A galvanized or coated steel sleeve with a uniform pattern of small circular perforations surrounds the pleated element. This sleeve serves three functions: (1) protects the delicate pleats from mechanical damage during handling, installation, and engine vibration, (2) prevents large debris - grass clippings, twigs, insects - from directly impacting and tearing the paper pleats, and (3) acts as a coarse pre-filter, deflecting larger particles before they reach the cellulose surface. The perforation density is balanced to provide structural protection without restricting airflow.

Products Application
Commercial Mower Fleet Maintenance
For landscaping companies, municipal parks departments, and sports field maintenance crews running fleets of B&S-powered mowers, air filter standardization reduces maintenance complexity and prevents the "wrong filter" downtime that happens when mechanics stock model-specific parts. One 75 mm B&S filter SKU covers five or more mower models in the fleet. Pre-season bulk replacement - swapping every filter in the fleet during spring servicing - eliminates mid-season filter-related call-backs where a mower loses power because the operator ran it for two seasons on the same clogged element.
500E / 550E Series Engine Applications
Briggs & Stratton's newer 500E and 550E OHV engines - 140 cc and 163 cc respectively - use the same 75 mm filter interface as the older flathead 1B20/1B30 series. These OHV engines run higher compression ratios and cylinder temperatures than their flathead predecessors, making clean intake air even more critical: dust ingestion in an OHV engine accelerates valve guide wear and rocker arm pivot degradation in addition to the piston and cylinder damage common to all engines. One filter upgrade services mower fleets containing a mix of older flathead and newer OHV engines.
Briggs & Stratton Walk-Behind Lawn Mowers
This is the filter's primary application. B&S 1B20/1B30/BS600 engines power the overwhelming majority of consumer and semi-commercial push mowers under brands including Victa, Masport, Murray, Mountfield, Snapper, and Craftsman. These mowers run 30–90 minutes per session in some of the highest-dust conditions any small engine faces - directly above a spinning blade that acts as a dust generator. A clogged filter restricts airflow, richens the mixture, fouls the spark plug, and robs the engine of the power needed to cut thick grass without stalling.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
