MANN+HUMMEL Develops New Flexible Air Filters For Tight Engine Compartments

The MANN-FILTER Flexline makes efficient use of installation spaces with curved external contours.

Installation space in a car is a rare commodity. Comfort functions, turbocharging, and much more have significantly reduced the available space in the engine compartment over the past decades. In response to this, the leading global filtration expert MANN+HUMMEL has developed new air filters with flexible external contours that make more efficient use of the available installation space. For the independent automotive aftermarket, they are available as MANN-FILTER Flexline C 26 017 and C 30 030 for the Mercedes-Benz A and B Class. The C 26 017 air filter is for gasoline engines and the C 30 030 is for diesel models. The use of further elements with flexible contours for other automotive manufacturers is planned.

Whereas flat air filters based on rectangular, trapezoidal, and polygonal forms with straight lateral edges were once the dominant design, the MANN-FILTER Flexline also makes efficient use of installation spaces with curved external contours. “We can accommodate a larger filtration area compared with conventional designs, and thus achieve higher separation efficiency and dust holding capacity,” says Daniel Schmid, product developer for Automotive Aftermarket Air Filter Elements at MANN+HUMMEL.

“With Flexline, we produce the air filter contours using state-of-the-art laser technology. This means that we can produce almost any shape that was not possible with the conventional method. With this laser technology, we are setting new standards in filter manufacturing,” emphasizes Schmid. Compared with filters with limited geometries and straight lateral edges, the C 26 017 air filter impresses with features such as 11% more filter surface area, 22% higher dust holding capacity, and 16% lower pressure loss. At the same time, the new Flexline air filters are also flatter than standard products, which means that can be used in particularly low installation spaces.

Mercedes-Benz was the first vehicle manufacturer to use the innovative solution, and is now using it as standard for its MFA2 (Modular Front Architecture) platform. The air filter will therefore be used in almost all four-cylinder gasoline and diesel engines from the A and B Class as well as their derivatives in the future.

MANN+HUMMEL has filed several patents for the manufacturing method and the design of the Flexline air filter with the German Patent and Trademark Office as well as in other countries.

This is always an important topic to discuss, because I consider excellent customer service one of the most important tools you can have to earn trust, respect and repeat business from the customers that come through your door. Whether that customer is do-it-yourselfer from across town or the professional repair shop across the street, your business depends on a solid relationship.It’s a subject that I am passionate about, and it’s one that many people are losing touch with. Whether you are communicating to someone in person, on the phone or using some type of social media, good customer service and bad can both exist. You can’t afford the latter, so this is the first in a series of topics which can and should be shared from the front of the shop to the back. No matter which role you hold, you represent the shop and yourself. Customer service should be your number one priority.First on the list is the greeting. From the second a customer walks in the door, they need to know you appreciate them coming in and how important they are to your business. First impressions are everything and here’s the correct way to do it each and every time: look them directly in the eye, smile and say hello!Of course, you can say “Good morning” or “Welcome to Joe’s Autocare,” but it should be a formal greeting and the most important thing is that you have smiled, looked them in the eye and recognized that they have walked through the door.You should always retain a formal greeting until you are on a first-name basis with a customer. Only once you have established that level of relationship is it OK to use the less formal greeting of “Hi,” followed by the person’s name.This greeting does more than just indicate respect and appreciation for someone walking through the door. Most likely there are customers both new and old who are in earshot of your conversation. For newer customers, this continues to build rapport and reinforce their positive view of your shop; they see that you demonstrate respect and treat everyone in the same manner. For repeat customers, even ones that have been coming for years, the greeting is important because the way you treat them is the reason they continue to come.And when a long-time customer comes in and you greet them with “Hi [First Name],” this indicates your appreciation for them and that you’re glad to see them as a person, more than just a customer. New customers that witness this will see that your repeat customers are comfortable enough to be on a first-name basis, another indication of the trust they have in you.
