Loncin Engine Air Filter for Snow Blower Engines
This is the air filter for the Loncin snow engine fitted to SONJUN snow blowers, supplied as a replacement service part for dealers, workshops and importers running a seasonal service programme. The filter keeps grit, salt dust and blown snow spray out of the carburettor and the cylinder, which is what protects the engine bore that a rebuild would otherwise have to replace. It is the cheapest consumable on the machine and the one most often left in place too long, so a clogged filter shows up as hard starting, rough running and poor power under load in the middle of the season. Because it is a fast moving line, it is worth ordering in depth with the machines rather than one at a time.
- Protects the carburettor and cylinder bore from grit and salt dust, which is where an engine rebuild bill starts
- Cheapest way to fix hard starting and poor power under load before assuming an engine fault
- Matched to the Loncin snow engine used on the machines, so it seats correctly in the housing
- Fast moving service item that is worth stocking in depth for a seasonal service programme
- Can be added to a machine order so filters are on the shelf before the first service
- Free replacement within warranty for quality problems, and at cost price outside warranty

Application Scenarios
- Annual pre season service on a dealer or municipal fleet

- Importers and distributors of SONJUN snow blowers
- Authorised dealers and independent service workshops
- Equipment hire and rental companies running their own maintenance
- Municipal and facility maintenance departments

Problems It Solves
- A clogged filter starves the engine and the machine is reported as underpowered when nothing internal has failed
- Grit and salt dust drawn past a damaged filter score the bore and turn a consumable into an engine rebuild
- Filters matched by eye do not seal in the housing and let unfiltered air straight into the intake
- Sourcing a low value consumable from a separate trader carries an MOQ and freight bill out of proportion to the part
- Fleets without filters on the shelf skip the pre season service and pay for it during the season

How It Compares
Against Generic aftermarket air filter
A generic filter that does not seal in the housing lets unfiltered air past the edge, which defeats the point of fitting one. This part is matched to the Loncin snow engine used on the machines.
Against Cleaning and reusing the old filter
A cleaned filter that has been through a salt and grit season loses sealing at the edges. Replacing it at service is cheaper than the bore wear it prevents.
Against Buying consumables from a separate parts trader
A low value consumable from another trader carries its own MOQ and freight charge. Here it ships with the machines or the rest of the accessory range on one order.
Use Guide
- Confirm the engine model and filter housing before ordering the replacement
- Stop the engine, let it cool and disconnect the spark plug lead before opening the filter housing
- Check that the filter seats fully on its sealing face so no air bypasses the element
- Replace the filter at the pre season service and again mid season on machines working in salt and grit
- Store spare filters dry and flat so the sealing edge is not distorted before fitting
