What is 

HOFFEN Epoxy 

HOFFEN Epoxy is a solid cast, monolithic epoxy resin, molded and ovencured 

as a solid, uniformly constructed product, offering excellent quality 

laboratory work surfaces and complimentary sink units. The impressive 

heat and chemical resistance of solid cast epoxy resin makes HOFFEN 

Epoxy the most popular choice for the rigors of a laboratory environment. 

The outstanding qualities of epoxy resin provide the safest, most 

economical and longlasting work surface available. HOFFEN epoxy is 

asbestos free. 

HOFFEN Epoxy surfaces resist discoloration, blistering, and cracking 

even under the harshest conditions. This extremely high chemical and 

heat resistance means DURATOP Cast Epoxy work surface and 

components, with proper maintenance procedures, will look like new 

after years of hard work in the laboratory or scientific environment. 

Solid cast Epoxy work surfaces do not depend on surface coating for 

protection or use low cost core material. Their strength and durability are 

built right into each sheet or sink. The smooth, matte, lowsheen finish 

eliminates distracting glare and is easy to maintain.

HOFFEN Epoxy 

Characteristics 

CHEMICAL RESISTANT 

HOFFEN is highly resistant against corrosive effects of most 

laboratory chemicals/reagent. 

FLAME RETARDANT / SELF EXTINGUISHING 

HOFFEN is flame retardant. In case of flame caused by 

flammable chemicals or Bunsen burner on HOFFEN surfaces, 

flame will not spread and will self extinguish in accordance with 

ASTM testing D635. 

HEAT RESISTANT 

HOFFEN will withstand high temperatures normally 

encountered in laboratory work (up to 193°C/380°F, based on 

ASTM D648 heat deflection test result). 

NONABSORBENT 

HOFFEN is nonporous, so liquids or microorganisms will not 

seep. No worries of potential inner surface damage or bacteria 

cultivation.

WILL NOT DELAMINATE 

HOFFEN is monolitihic / homogenous solid cast epoxy which is 

nonporous so it will not delaminate, swell or spall like some 

other materials.

Fume Hoods 

For Todays Industry 

Fume hoods, also known as fume cupboards, are enclosed safety devices aerodynamically designed to remove toxic and noxious gases produced when 

chemicals are mixed or tested. Within the double layer, steel epoxy powder coated superstructure, there is an inner chamber that promotes the efficient 

removal of fumes and reduces personnel risk of exposure to hazardous chemicals. Industry advances created various composite panels that are heat 

retardant, chemical resistant and moldable in the form of a white fiber / glass reinforced plastics (FRP / GRP) and are now considered the most commonly 

used inner chamber and baffle materials for todays fume hoods, along with Epoxy bases or work surfaces.

HOFFEN FAN 

Chemical Resistant Centrifugal fan 

Centrifugal Fan 

Fume extraction systems, for use within the fume hood or fume cupboard in all 

laboratories, is a critical element of safety and maintaining control of corrosive 

chemicals and gases. Personnel protection must be maintained at all costs and 

that is the reason the latest generation of Polypropylene Centrifugal Blowers / 

Fans have been developed for the laboratory market. 

Polypropylene (PP) materials lend themselves to molded configurations that allow 

for ease of air flow, ease of maintenance, provide excellent ventilating properties 

while providing a sturdy, compact design with low level sound and high efficiency 

capabilities. All components of the HOFFENFAN blower are made of Molded 

Polypropylene (PP) and provide excellent protection against corrosive fumes and 

aggressive exhaust vapors. HOFFENFANs may be installed outdoors and are 

supplied with a suitable cover to shield against the attack of UV radiation. Fans 

are easily maintained due to their two part molded construction. 

FIELD OF EMPLOYMENT 

HOFFENFANs are installed wherever moist, acidic or chemical fumes are 

present in the fume hood and ducting system. The HOFFENFAN eliminates the 

vapors within the ducting and the fume hood making the laboratory environment 

safe and productive for future experiments and testing procedures. Blower / fans 

with varying horse power motors are incorporated within the laboratory in such 

facilities as K12 schools, university, hospitals, water treatment plants, 

pharmaceutical operations, petrochemical facilities and similar applications. 

ROTATION 

The forward curve centrifugal 

housing and impellers can be 

positioned in eight (8) different 

configurations in 45 degree increments, 

based on the 

available spacing and configuration of 

roof or ceiling 

mounting locations. Both clockwise and counter clockwise applications may be 

utilized. 

DEPENDABILITY & MAINTENANCE 

All HOFFENFANs are quality controlled and tested for dependability and wear 

ability. Their sound and technically advanced construction provides long lasting 

dependability and proper extraction of chemical fumes and hazardous vapors. 

Owner or maintenance personnel must undertake annual reviews and inspection 

checkups as recommended by supplier to assure the continuous operation of the 

fans and their components. 

WARRANTY 

HOOFENFANs are warranted for one (1) year from time of purchase and warrant 

that all Fans / Blowers and their Motors are free of production defects in 

workmanship and materials used. Proper maintenance must be conducted on all 

parts within the warranty period and beyond. Warranty will be voided if damage to 

the impeller, housing etc is caused by improper installation or wiring of all 

connections. 

MATERIALS 

HOFFENFAN's are produced of High density (HD) Polypropylene plastics and 

the base motor is made of galvanized steel. The motor support and mounting 

attachment stands are also made of high grade steel. The housing is constructed 

of high density PP in order to provide maximum resistance to corrosion or attack 

by harsh chemicals. Fiber glass or FRP (fiber glass reinforced plastic) 

construction is also available upon request. The impellers and casing / housing 

are to be used in temperatures up to but not exceeding 180 degree F or approx. 

80 degree C.

EMERGENCY DRENCH 

SHOWER & EYEWASH 

In the complicated process of selecting emergency eyewash and drench shower 

equipment for schools or private sector applications, with design and ease of function 

as the main criterion, specifiers must select, in compliance to regulatory requirements, 

the proper materials. Emergency eyewash and shower units are designed to deliver 

water quickly and completely, to rinse contaminants, such as fumes or particulates, 

from the users eyes, face or body. These products are not substitutes for the safe 

handling of hazardous materials be it on a counter top work surface or within a fume 

hood, but they are the first line of defense and should be considered carefully. 

*All Dimensions 

indicated 

Are 

in 

Millimeters(MM) 

HOFFEN water systems offer fairly comprehensive and advanced emergency 

eyewash and shower units. The products are characterized by aesthetic appeal, 

space saving styling, and enhanced performance. Floor mounted or table mounted 

eyewash or shower units, when placed in ADA compliant or handicapped accessible 

areas, require minimum knee clearance and minimum location from obstruction. 

HOFFEN eyewash and shower units are made in compliance with American National 

Standards Institute (ANSI Z358.1). This requirement in part details that the 

emergency equipment should be located in an accessible area nor more than 10 

seconds or 30.5 meters from a hazardous location. The emergency equipment must 

be connected to a potable water supply, having a minimum flow pressure of 3 bar (45 

psi) and maximum 5.5 bar (80 psi), with discharge water temperature at a comfortable 

range from 60F to 95F (15C to 35C). 

Whether your requirement is for water fixtures, gas taps, eyewash or shower units, all
