Your Air Filtration Tools Guide

The air filtration tools are really necessary when you are facing any respiratory problems. With this article you are sure to get all the information on air filtration tools.

The air filtration systems are used to clean air by removal of pollutants, dust, bacteria, pollen or simply anything that is floating through the air. it is possible to get clean air and so many health problems and diseases can be avoided with the help of air filtration. You get fresh air (disease and germ free) to breath in.

You will find lot many uses of these filtration systems in industries as well as households. To meet the various needs these filtration systems come in various models and materials. For ex. filtration systems are used in households, cars, aircrafts, industries, buildings ventilation systems, mechanical engines such as air compressors, gas compressors, diesel engines etc. The air filtration system can be found in various makes and models and simply changes with every use.

The home filtration unit or system works wonder in the house by cleaning the home air which minimizes the risk of possible allergies and other related problems due to the foreign particles. The filtration system is best judged by the material used in it, the CFM (air filtered at Cubic Feet per Minute) and other features.

It should be chosen keeping in mind the type of unit where you want to put that, the area size which will require pure air and the output CFM of the system. For industrial or commercial purposes more advanced and powerful filtration systems or a thick air filters compared to home version are used.

Compressed filtration systems are tools, which are used to remove water, oil, oil vapor, dirt, and other contaminants from a compressed air supply. This is very necessary for the compressed as it has a high percentage of air contamination due to microscopic foreign particles.

The commercial filtrations are used for large establishments such as a multistoried building or hospitals the amount of air pollutants present in the air is high and hence require larger air filters with thicker filters and larger CFM's. Such air filtration systems are very useful for cleansing large quantities of air with almost 95% cleaning.

In commercial many different filtration techniques such as HEPA air filters, electrostatic air filters, ionic air purifiers etc are used. One such popular technique, filtration technique is the dry scrubbing pas phase air media.

These media remove airborne gaseous contaminants via adsorption by capturing gaseous molecules and holding them to the media's surface and/or chemisorptions i.e. reacting with gaseous molecules and changing their chemical form to a nontoxic end product. This media is available as dry, spherical pellets for bulk fill of modules or secured in a pleated bi-component fiber filter.

Another filtration system is electrostatic filtration system used for household or commercial purpose and uses electrostatic and carbon filters to clean the air. It is most effective flirtation system to get relieved of pollutants and micro particles from the air.

The functioning of the electrostatic air filtration is different from the HEPA but is more effective in filtering the air clean. An electrostatic carbon filtration system also cleans tobacco smoke and other such odors and keeps your lungs healthy by giving clean air for breathing.

How to Change Your Car's Motor Oil

By Stephen Bucaro

First, let's answer the question; Why should you change your own oil? Because you can save time and money. You don't have to wait in line at the service garage or quick oil change shop. For ten bucks you can get the best oil and a brand new oil filter. And, it's so easy to do that you could train a monkey to do it.

Changing your cars motor oil is a very simple three-step process: 1. Drain the old oil. 2. Replace the oil filter. 3. Add the new oil. But before we go through the steps, lets answer a few basic questions.

When should I change my oil?

Look in your cars owners manual. Most auto manufacturers recommend changing the motor oil every 6,000 miles for normal service, or every 3,000 miles for severe service. I change my oil every 6,000 miles, and my engines run like new when I trade my vehicles in with well over 100,000 miles on them. One thing that I do is change a new cars oil after the first 300 mile break-in period. Then, after that, I change the oil every 6,000 miles.

What kind of oil should I use?

You are not going to save money by using an off-brand oil because your engine will wear out sooner. Use oil that meets the American Pertroleum Institute (API) classification SL. I use Valvoline, Quaker State, Pennzoil, or Havoline brand oil. These quality oils contain additives that make them work better and longer.

If you are changing your oil just before winter, use SAE 10W30 weight oil. This number means the oil will have a thin 10 weight viscosity when the engine is cold, helping the engine to start easier, and then the oil will thicken to 30 weight viscosity when the engine warms up, protecting the engine better. If you are changing oil just before summer, use SAE 10W40 weight oil. The extra 40 weight viscosity will protect your engine better when it's hot.

What's the First Step?

First let your engine cool off. Modern engines run at close to 300 degrees (F) and hot oil will definitely give you a severe burn. You shouldn't have to jack your car up unless you have some kind of ground hugging sports car or low rider. Almost all cars have enough space underneath to reach under and change the engine oil.

Step 1: Drain the old oil.

Locate the oil drain plug and place a pan under it to catch the oil. With a box wrench, remove the oil plug.




If you have a GM dual-overhead-cam EcoTec engine you may have a difficult time locating the drain plug on all that aluminum.

When the oil stops draining, reinstall the drain plug.

Note for newbies: To replace the drain plug turn it clockwise. Start the plug with your fingers. If it seems even slightly hard to turn, back it out! You are crossing the threads.

Step 2. Replace the oil filter.

Move your oil catch pan under the oil filter. Using an oil filter wrench to get it started, remove the oil filter. (newbies: counter-clockwise, and you will get some oil on your hand.)

Pictured above is a strap type oil filter wrench. This is the best kind to use.

Pictured above is a socket type oil filter tool. You use this type with a ratchet just like a regular socket. The problem with the socket type is that it tends to get stuck on the filter. Use the socket type tool if you don't have enough clearance around the oil filter to use the strap type.

With your finger put a thin coat of oil on the new filter's gasket to make it seal better.

!!! Now pay attention - here's were you can screw up royal!

With your hand, install the new oil filter. If it seems even slightly hard to turn, back it out! You are crossing the threads. Most filters have an instruction printed on them to give the filter one more turn after the gasket has made contact.

Here's what I recommend: screw the filter on until its "hand tight". Then use the oil filter wrench to snug it up another 1/8 to 1/4 turn. This is critical!

When the vehicle is running, the oil pump puts the oil under pressure. If you don't install the oil filter tight enough, the oil will come gushing out. If this happens Shut down the engine immediately! Without oil, an engine will lock up within seconds.

The first time I changed my oil, I used the filter wrench to tighten the filter as tight as I could get it. Wrong! The next time I went to change my oil, I couldn't get the filter off. Luckily I had plenty of room around the filer, so I hammered a screw driver through the body of the filter and used the handle of the screw driver to turn the filter off.

Warning! Don't over-tighten the filter. Follow the instructions above carefully!

The GM dual-overhead-cam EcoTec engine has an unusual oil filter located on top of the engine. This picture shows the engine with the air intake hose removed. That's the oil filter canister just to the right of, and below, the end of the open air intake tube. Use a proper size wrench to remove the canister lid.

The GM dual-overhead-cam EcoTec engine uses a filter cartridge. Shown above is the filter cartridge and the filter canister lid.

Step 3. Add the new oil.

Locate the oil filler cap on the valve cover. I've seen newbies pour motor oil in everything from the master brake cylinder to the radiator cap. Make sure you have located the the oil filler cap. Remove the oil filler cap.

When pouring the oil, hold the oil "can" as shown. You would be wise to use a funnel between the oil can and the valve cover oil filler hole.

How much oil should you add? Look in your cars owner manual. Most engines have a capacity of four or five quarts. Don't overfill the crank case. When you run the engine the extra oil will be blown out through the PCV value, possibly stalling your engine.

Tip: If you don't know the oil capacity of the engine, add four quarts, then check the oil level, if it's a quart low add another quart.

Replace the oil filler cap.

Step 4. Start the Engine.

Yes, I know, I said there where only three steps. You're finished, this is not really a "step".

Start the engine and make sure the oil warning light goes off. Look under the vehicle to make sure oil is not leaking out. Turn off the engine and let it set for a minute to let the oil drain down to the crank case. Then use the dip stick to check the oil level.

How to check the oil level: Remove the dip stick, wipe it clean with a rag, reinstall the dip stick. Make sure the dip stick is in all the way or you will get a false reading. After a few seconds remove the dip stick and examine how far up the stick is covered with oil. Most dip sticks have a “full” mark printed on them.

Note: I find the best way to dispose of the old oil is to use a funnel to pore it from the collection pan into the bottles from which the new oil came. When I get a big pile of used oil bottles I bring them to the oil recycling center. Be sure to mark the used oil bottles so you don't accidentally think they are new oil.
