No. Filtration testing measures the percentage of dust retained before the filter reaches a terminal test pressure, often 10” of restriction above initial restriction. We use airflow as a simplified term to explain a more complicated physical process. The more precise description is restriction: K&N air filters create less restriction which helps an engine run better. An engine will only use the air it needs and our air filters do not result in an engine using more air than necessary.

There is a great deal of confusing and misleading information being circulated as "airflow data." Sometimes the airflow is stated as "free air" or is given without reference to the static pressure (SP). Both ignore the flow restrictions imposed by vacuum hose, filters and other system components. Other published rates have never been tested or verified using established industry testing protocols.

No, an engine can only take in a fixed volume of air depending on the engine’s size. The more restriction that an air intake system (filter, air box, and tubing) causes, the greater the potential is for power and mileage degradation.

It should be noted that the EWI4000s was designed with a semi-open airflow system. That is to say that unlike what your teachers may have taught you, you SHOULD let some air escape from the corners of your mouth when blowing into the EWI4000s. This type of system allows for far greater control over air flow by the player and feels exactly the same as blowing all the air through the horn.

With a charcoal grill, air circulation keeps the coals burning. Having the bottom vents open during preheating aids in starting the fire and in maintaining the heat. With a propane grill, leave the lid closed at all times, so the heat circulates around the food.

In some situations barbecue smoker users find that there is not enough airflow around the smoker to generate enough heat, or worse still, provide inconstency when cooking giving wildly varying results to the cooking. Many smoker users find that the best way to improve the performance of their barbecue smoker is by cutting away small sections of the smoker, or drilling holes in the right places.

The battery manufacture is responsible for determining the amount of gas that is needed to pass through the flame arrestor during a given period of time. This is determined by the size and design of the battery, and the size and thickness of the flame arrestor. Samples are available for testing and design purposes.

Yes, solar screens installed properly will not inhibit the operation of your window. However, some airflow will be restricted due to the thickness of the material.

No. Since SDS is fully programmable and designed to work on almost any engine, we decided to use the speed/density method of load sensing. Installation of airflow meters on many vehicles, especially turbocharged ones, is often awkward because of their size. Airflow meters also represent a flow restriction which is not conducive to making hp on performance applications.

The majority of homes are not airtight. There is enough air flowing from the doors, windows and openings. Air pressure and flow can be affected by any combustible appliance (i.e. furnace, gas dryer) or ventilation unit (i.e. bathroom fan, attic fan). We therefore recommend that the Humidex be installed at least 10 ft. away from any furnace in order not to interfere with the air flow.

There is no simple answer to this question because the airflow is very dependent on the length of the venting pipe and the number of bends it contains. Villa and Weekend have condensation collectors and therefore do not need to be insulated. Chalet – using free-blowing ventilation or a fan – must have insulated venting pipes.

No, they don't. A bus radiator is on the side of the coach and the cooling fan has to pull air through it. On a truck, as soon as you get up to 35 MPH, air is pushing its way into it. The front radiator is a far superior design for a truck that works much heavier carrying an average weight of 80,000 lbs., where a bus seldom carries more than 40,000 lbs. The side radiator design for a bus is very adequate that engine.

A 4 cylinder engine requires about 1000 cfm (1700 m^3/h), a 6 cylinder engine requires 1700 cfm (2890 m^3/h) and a small V8 about 2100 cfm (3570 m^3/h). To reach the minimum cfm required you may need to install two or possibly more fans.

There is a big difference as one unit is directly measuring pressure while the other is measuring airflow direction. Units that list the capability of measuring flow rates of .0001” WG are air flow monitors not pressure monitors. This capability is inconsequential for monitoring isolation rooms because a negative pressure reading as low as -.0001” is virtually insignificant in the air pressure differential between the controlled space and the referenced space to be compliant.

previously stated, since it is measuring airflow especially in a hospital environment many uncontrollable factors will influence the readings. Elevators on a floor sometimes cause a vacuum as the doors close and they ascend or descend causing a vacuum in the corridor. Laundry carts passing the probe head create an uncontrolled air movement affecting the air flow direction.These are just two examples of actual occurrences that were recorded by users of air flow monitors.

We recently did some dyno testing at Wheel to Wheel in Michigan on Mark Stiewlows new 400 CID, 600 HP engine. With S-tube Stainless Works mufflers and complete exhaust system, we were down 1 hp at peak, but made more average torque and horsepower than with no mufflers. With a chambered muffler that is approximately 6 DB quieter than our first muffler, we were down about 15 flywheel HP compared to open headers.

If you have the need to direct the airflow all that's required is a 1 1/2 inch PVC Elbow. Simply place it over the exhaust port for 360 degrees of movement! Ideal for stationary use to direct the air to a specific area! Because of the high demand and excellent use of this item it is now available on the KoolerAire order page.

Several of the RP materials can be used for waterflow and airflow testing without leaking. Some of the materials must be infiltrated or coated to achieve this and some are classified as solvent-resistant. Of course the specific solvents and time of exposure are key to a material's performance.

The heat exchanger installed on the lowest level of the rack blows the cooling air with a temperature between 20 and 25 °C (ASHRAE-Standard) from below to the front of the server. Each server takes in its cooling air from the front and releases it to the rear with a temperature increase, depending on equipment. The heated air is in turn sucked up behind the servers and pushed with redundant fans through air ducts in the rear door down into the heat exchanger.

If you need to ask this question, leave the MAS honeycombs alone! They're designed to straighten out the airflow so the MAS can obtain accurate airflow readings. Taking them out will reduce the air flowing over the MAS, which makes the readings innaccurate. A person with enough knowledge to be dangerous may reply "but all you're doing is reducing the airflow count, leaning out the engine a bit" -- which is correct to a certain extent.
