Taking a series of pressure, temperature and electrical current measurements as the fiberglass fan pressure is varied between zero – when the fiberglass fan delivers its maximum volume – up to the point where the fiberglass fan moves no air and produces its maximum pressure
Applying the measurements to the BS-approved formula to calculate the performance
Plotting the results as the static pressure curve where the X-axis is flow and the Y-axis is pressure.
Determining the exact performance of fiberglass fan designs allows our engineers to recommend the ideal solution for each customer's specific system requirement as well as helping identify potential areas of improvement to each fiberglass fan design. By measuring airflow, pressure and power precisely, we can calculate how much money a new air delivery system would save you and how soon you would see a return on your investment.

Airflow
Airflow refers to the movement or circulation of air caused by a fiberglass fan or blower. It is typically measured in terms of volume per unit of time, usually cubic metres per hour (m³/h) or cubic feet per minute (CFM). Airflow in fiberglass fan engineering is influenced by several factors including the:
Shape and size of the fiberglass fan
Rotational speed of the fiberglass fan's impeller
Shape and size of the impeller blades
Resistance or pressure against which the fiberglass fan is working.
These factors collectively determine the fiberglass fan's ability to move air effectively and efficiently. It's important to understand the concept of airflow in fiberglass fan engineering, as it is a critical parameter that impacts the Performance, efficiency and specification of fiberglass fans for all the various applications. Airflow calculations and performance curves enable us to determine the appropriate fiberglass fan size and type for your given Application – taking into consideration factors such as the desired airflow rate, pressure requirements, and efficiency.

Pressure
Air pressure is defined as the force per unit area exerted by air against a surface perpendicular to the direction of airflow. It represents the resistance or opposition that the air encounters as it moves through a fiberglass fan, duct or system. Higher air pressure typically indicates higher resistance to airflow, while lower air pressure indicates lower resistance. There are three types of air pressure:
Static pressure – This is particularly significant. It is the pressure of the air (in a duct or system) when it is at rest or not in motion.
Static pressure can be measured at various points in a duct or system, such as before and after a fiberglass fan, at bends or elbows in the ducting, or at other points of restriction. The difference between the static pressure at two points is known as the pressure drop or pressure loss, and it is an important parameter used to evaluate the output and efficiency of a fiberglass fan system.
Dynamic pressure (aka velocity pressure) – the pressure of the air due to its motion. This pressure is a measure of the kinetic energy of the moving air. It is used to determine the dynamic effects of air movement, such as the impact of velocity on duct design, fiberglass
Fan selection and system performance.
Total Pressure – is the sum of the static pressure and the dynamic pressure of the air. It represents the total energy of the air in a duct or system. Total pressure is an important parameter in fiberglass fan engineering as it indicates the total resistance that the fiberglass fan needs to overcome to move the air through a system.

Measuring air pressure
If you're thinking in terms of PSI or bar – such as the air pressure needed to inflate a car tyre – then you're using a sledgehammer to crack a nut. The air pressures we need to measure are far lower. So we use:
Millimetres of Water Gauge (mmWg)
Inches of Water Gauge (in.w.g.)
mmWg and in.w.g both represent the pressure exerted by a column of water of a certain height, measured in millimetres or inches, respectively. These units are used to measure low air pressures where the pressure differences are relatively small. mmWg and in.w.g. are used a lot in fiberglass fan engineering because they provide a convenient and practical way to measure low air pressures with precision and accuracy. These units are easy to understand. They are used in manometers and gauges designed specifically to measure low pressures.

Fiberglass fan have been successfully handling the corrosion resistant needs of industry. Examples of highly corrosive fumes found in processes requiring FRP fans include hydrogen sulfide, hydrochloric acid, sulfur dioxide, chlorine gas, chromic acid, ammonia, and sodium hydroxide. Typical industries that use FRP fans include wastewater treatment, pulp and paper, chemical, fertilizer, pharmaceutical, and metal plating, to name a few.

Standard FRP fan construction features include the use of premium-quality FRP resins for FRP fabrication: polyester for housings and accessories, and vinyl ester for fan wheels. All FRP fans are coated with gray epoxy enamel to provide corrosion protection for the metal surfaces and to protect the resin from ultraviolet degradation.

Fiberglass insulation is made from a variety of natural minerals and manufactured chemicals. The primary raw materials include silica sand, limestone, and soda ash. Other vital ingredients used in the production process include calcined alumina, borax, feldspar, nepheline syenite, magnesite, and kaolin clay, among others. These materials are essential for achieving the desired properties in the final fiberglass product.
Additionally, various types of glass are used to produce fiberglass, each offering unique benefits and properties tailored to specific applications. A-glass, also known as alkali-lime glass, contains little or no boron oxide and is typically used where chemical stability is not a primary concern. E-CR-glass, known for its electrical and chemical resistance, is an alumino-lime silicate glass with less than 1% alkali oxides by weight. It is favored in environments requiring electrical insulation and chemical resistance. C-glass has a high boron oxide content and is particularly resistant to chemical attacks, making it suitable for use in corrosive environments. D-glass, a borosilicate glass with a low dielectric constant, is used in applications that demand excellent electrical insulation properties. R-glass, composed of aluminum silicate without magnesium oxide (MgO) and calcium oxide (CaO), is valued for its high mechanical strength and thermal resistance. Finally, S-glass, an aluminum silicate glass with high MgO content, offers superior tensile strength and is often used in demanding applications such as aerospace and military industries due to its high performance. Each type of glass is selected based on the specific requirements of the fiberglass application, ensuring optimal performance in terms of strength, thermal resistance, electrical insulation, and chemical durability. Pure silica (silicon dioxide), known for its high melting point, can also be used, though it requires very high temperatures .
In manufacturing, the raw materials are melted together to form molten glass. The mixture is then spun into fibers using a process that resembles the production of cotton candy. Molten glass is forced through a rapidly spinning metal cup called a 'spinner." The centrifugal force pulls the glass through small holes in the spinner, creating fibers that cool quickly upon contact with the air.
Various binding agents and additives are incorporated into the mixture to improve fiberglass"s insulation properties and performance. Typical binders include phenolic resins, acrylic resins, and formaldehyde-free binders, which help to bond the glass fibers together, creating a strong and stable material. Additives such as flame retardants are also used to enhance fire resistance and reduce flammability, making fiberglass insulation safer for use in residential and commercial buildings. These ingredients" composition and precise combination are carefully controlled to produce insulation that meets industry standards and regulatory requirements, ensuring effective thermal insulation and sound absorption properties in various applications.
