Fans & Megtec Division

Fans ProtcentreThe ZVVZ a.s. manuacturing program includes an extensive range o axial and radial

ans which are used in all spheres o human activities. In a sense, they are make

the heart o air-conditioning technology. Perhaps, all air-handling acilities consist

o ans they are the mainspring o airow and pressure necessary or combustion,

they exhaust ue gas, transport ingredients, aerate loose materials

Fans carrying the ZVVZ a.s. label can be ound in signicant buildings in the Czech

and Slovak Republics, but also in Europe, Asia, Arica and even in America.

Currently we manuacture axial ans with the impeller diameter ranging rom 500 mm

up to 10,400 mm and radial ans ranging rom diameter 400 mm up to 2,500 mm.

At customers request, we can supply ans with a special surace nish, made in

stainless steel, seismically resistant ans, etc.

Fans & Megtec DivisionFans ProtCenter is involved in the production and supplies o small and big ans including spare parts and service. We ocus on

Fans designed or wind tunnels and climatic tunnels

ZVVZ a.s. supplies ans or wind and climatic tunnels. It is possible to supply

both main ans and auxiliary and service ans or these types o tunnels. The

ans comply with the strictest requirements demanded or such equipment

and the ans can operate in climatic, acoustic or energy tunnels. Rotating

an components are made o steel or aluminium, or can be delivered made

o composite materials, which complies with extreme requirements needed

or acceleration or deceleration o the transported air. In developing

these products, ZVVZ a.s. cooperates with oremost R&D institutes, which

makes it possible or our company to ofer products based on the latest

knowledge and to give to our customers advantages to be one step ahead

o competitors.

Measuring o air technical parameters in ans is divided into testlaboratory measurements or tests during operation. ZVVZ can

make problem-ree normative measurements using standard

digital manometers and the collected data are subsequently

processed semi-automatically.

Aerodynamic tests always run in three stages, on a 600 mm

diameter testing line:

1. measuring o aerodynamic class characteristics

2. probing o ow patterns in selected operating points

3. measuring o perormance areas o the whole eld

Measurement o aerodynamic characteristics usually

includes measuring o the ollowing parameters:volume ow rate
