AF26187: The “Gatekeeper” Hidden in The Engine Compartment Of the Forklift
1. Talk About AF26187
But as long as it has problems, the engine will be out of breath, the forklift will break down, and the portable generator set will also go on strike.
It is the air filter.
Today, we will not talk about universal filters or OEM originals, but only about one thing: AF26187. An air filter developed and produced by our own factory, used to replace the OEM filter used by the original Cummins B3.3-G2 engine, quietly doing important things.
2. Where is this filter installed?
AF26187 is designed specifically for Cummins B3.3-G2 engines. This model is not unfamiliar. It is widely used in:
Small or portable generator sets
Forklifts used in the field of warehousing and logistics
Equipment such as sweepers and aerial work platforms for urban ground maintenance
Backup power equipment at construction sites
To put it bluntly, it does not serve “luxury cars”, but those guys who work silently under the scorching sun, on construction sites, and in warehouses.
These equipment have one thing in common: a lot of dust, long working hours, and fast replacement rhythm. The air filter is the most often ignored, but the most unbearable part.
3.Who is purchasing AF26187?

In our contact with customers, the buyers of this filter are usually not ordinary end users, but the following:
- Forklift after-sales service companies
They do not sell complete vehicles, but have hundreds of maintenance orders for forklifts. They need:
Cost-effective replacement filter elements (the original ones are too expensive, so customers are reluctant to buy them)
Stable supply, standardized packaging, easy storage
Bulk delivery + regular purchase agreement
- Power generation equipment maintenance companies
Especially companies that provide on-site services for construction sites and remote projects. Their requirements for filters are simple and direct: durable, no failures, and easy to replace.
- Small power system importers/wholesalers
These customers are usually distributed in Africa, the Middle East, and Southeast Asia. They have to face terminal maintenance customers, distributors, and government procurement projects. They need:
Price-competitive replacement parts
Factories that can quickly purchase and distribute goods according to project cycles
4. Why do customers choose AF26187 produced by us?
We are not a marketing company, nor do we take the route of “brand filters”. We are a down-to-earth factory specializing in replacement filters.
But because of our focus, we know where the customer’s pain points are:
✅ 1. The product does not look like it, but it can be installed and used
AF26187 We make real replicas. We have the original machine sample of Cummins B3.3-G2, and we have used the actual machine to test the assembly accuracy, sealing position and differential pressure flow.
Our goal is not “almost the same”, but “can be replaced”.
✅ 2. The filter material is not cheap paper, but an engineering-grade composite paper layer
We use high-density filter paper, which has been coated and can maintain 99.5% filtration efficiency in a humid and dust-rich environment.
It is not the kind of filter element that softens after two days of suction, but a product that can really last until the recommended core replacement cycle.
✅ 3. Each batch of shipments can be traced and OEM-labeled
For wholesalers and project-based customers, product batches, quality inspection data and outer packaging consistency are very important.
We support: laser coding, OEM number marking, carton inner bag customization, MOQ flexible negotiation.
4. The details of AF26187 are not only written on the label

In the filter industry, there are too many marketing words, but the equipment uses real goods.
You don’t have to buy our AF26187, but you can compare us:
Whether it matches the original factory size;
Whether there is a third-party loading test;
Can we discuss packaging and ordering rules;
Is there inventory to deal with urgent orders;
Whether we can cooperate with you to make project delivery and filing materials.
If you care about all these, we can talk about it.
Ending A word to wholesalers:
AF26187 is a small-volume, high-repurchase product. It is easy to ship, small in size, and has controllable profits. It is not a brand promoted by advertising, but it wins orders by “being able to be installed and used”.
If you happen to need this kind of product, please contact us.
