Ventilator Noise Problem
By: oleg tchetchel
Some cures for fan noise problems are:
- Select a different fan. Computerized selection routines allow us to examine many fan types looking for the quietest. Use a custom fan design, if required.
- Relocate the fan to where sound is not a problem.
- Vibration isolation and flexible connectors on the inlet and discharge will reduce structure-borne noise.
- Insulate or acoustically enclose the fan housing if housing radiated noise is a problem.
- Add silencers or duct lining to inlet and / or discharge to reduce sound in these directions. However, a silencer on the outlet does not reduce the housing radiated noise or inlet noise; and an inlet silencer does not affect the housing radiated and/or outlet noise.
- Look for ways to reduce system resistance since sound output is proportional to fan static pressure.(read

How To Increase Ventilator Performance
By: oleg tchetchel
Industrial processes and plant ventilation systems often need more air than originally designed. Increased production requirements, process changes, and facility renovations are a few of the major reasons. Additionally, the lack of adequate maintenance over time can negatively impact system airflows. This article discusses several procedures that can increase airflow. Often airflow can be increased by adhering to proper fan maintenance procedures as outlined in fan installation and maintenance literature.(read

Fan Blower Performance Curve
By: oleg tchetchel
Fan curves are based on laboratory test data and are sometimes referred to as "test curves". A typical test curve will often define the performance parameters for a specific design and size of fan, operating at a given speed, moving a gas of a given density. Inspection of this graph will show that it is actually composed of four separate curves.(read

Fans Vibrations
By: oleg tchetchel
There is a trend in the fan industry that is causing significant changes in fan design and in the manner in which fans are marketed. As a result of the maturing vibration measuring instrumentation market, computer software and maintenance training programs have been adapted which equate “low vibration” with long life, igher quality, and lower maintenance costs. The fan manufacturers used to be the “vibration experts” and set the tolerance for acceptable levels of vibration.(read

Industrial Gas Scrubber
By: oleg tchetchel
Gas scrubbers are applied where removal of fine particulate from corrosive, hazardous or volatile gas streams is required. Venturi scrubbers wash dust and particles out of the air by forcing the air into a spray chamber, where fine water particles cause the dust to drop from the air stream. Where applied, venturi scrubber technology is able to achieve the highest particulate collection efficiency of any wet scrubbing system.(read

High Temperature Exhaust Ventilator Fan
By: oleg tchetchel
The main purpose of the NFPA can be summarized into three main categories. First, NFPA promotes the science and improves the methods of fire protection and prevention, electrical safety, and other related safety goals. Secondly, it obtains and circulates information on these subjects. And thirdly, it secures the cooperation of its members and the public in establishing proper safeguards against loss of life and property. The fourth organization is Underwriters Laboratories, Inc.. UL is a non-profit, independent organization that maintains and operates laboratories for examination and testing of devices, systems and materials to determine their relation to life, casualty hazards and crime prevention. UL has three safety standards that apply to emergency smoke exhaust products. UL705 is concerned with the mechanical and electrical construction to insure safe operation. All electrical components (motor, wiring, switches, enclosures, etc.) must be ULlisted. UL793 is concerned with the lifting mechanism for the butterfly dampers and the fusible link. In order for a product to be listed in the UL Directory under ÒPower Ventilators for Smoke Control Systems,Ó it must meet the requirements of both UL705 and UL793. Additionally, UL must witness a full-scale test of a fan operating for the required time at the specified elevated and temperature.(read

Process Fans For Industry
By: oleg tchetchel
To reduce greenhouse gases and produce a useful byproduct, many countries, states, counties, and cities are replacing landfills with industrial composting systems. One of the most common methods for large scale operations is Aerated Static Pile or Active Aeration composting. ASP refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. Our fans play a key role in these systems by forcing air through an array of perforated piping placed in and around the compost material to provide air circulation for controlled aeration. This allows system operators to maintain the desired temperature, moisture, and oxygen levels within the piles during decomposition.(read
