In Air Filters It’s … Small Engines (Large Appetites?) 650533

Close analysis of what occurs during the time of air intake in a small engine shows that the rate of flow of air is six or more times the engine’s actual consumption rate of air. This high transient air flow places unusual requirements on air filters for small engines both from the standpoint of ruggedness and porosity. For maximum utility air filters for small engines must be easily serviced (cleanable and reuseable on the job even if only on an emergency basis).
