Square Filters FV

Trevor Ellis — Thu, 12 Feb 2026 10:50:40 +0000

PETKUS Square Filters FV are used in grain processing plants for dust removal in exhaust air. The dusty air is aspirated by the fan which can be placed directly on the square filter or separately. The filter separates the dust on its way through the bag filters and the cleaned air is transported outwards. Dust is removed pneumatically from the filter bags. The dust is discharged over a filter hopper with an auger and a secondary rotary valve.

Characteristics

Bolted housing made of galvanized sheet steel with access door and feet
High flexibility due to various sizes and modular design
Filter bags made of polyester needle felt (PE)

Technical Data:

				FV 36		FV 48		FV 60		FV 72
Filter Area		(m2)		21.6 – 43.2		38.4 – 57.6		48.0 – 72.0		57.6 – 86.0

Smooth Wall Silo

Trevor Ellis — Thu, 12 Feb 2026 10:50:39 +0000

PETKUS Smooth Wall Silo is a modern and efficient silo system for storing products such as seed or compound feed which must be completely emptied from the bin. Similarly, powder, fine seeds and generally poor-flowing products that require complete removal after storage can be stored here as well as products that must remain absolutely contamination free.

The modular design silo cells with different heights and capacities can be installed as a battery of silos in a row or as a block. The steel construction for a machine house can be integrated into any silo concept. The smooth double wall elements with 135 ° corners, as well as the use of flat head countersunk screws in the area of the silo supports prevent product adhesion. During emptying almost no grain remains in the silo. With the sandwich type construction, the double wall elements are inserted horizontally and are vertically bolted. Every double wall element is equipped with a lateral structure with a quarter support. During installation a hollow cavity is created, which is filled with concrete afterwards. With extremely high silo cells, silo supports can be provided with reinforcement baskets before the filling of concrete. This contributes to the static stability of the silo system. Every silo cell is equipped with a bolted or welded hopper with a spot or slot outlet.

Characteristics

Model in a cathodic dip painting (KTL) with a coating of the cavities
Double wall elements with a length of 2000 mm, 2500 mm, 3000 mm, 3500 mm, and 4000 mm
Cell outlet hopper with spot or slot outlet
Substructure, frame, ladders and operating platforms
Loading hopper available
Complete solution including machine house (steel construction) possible

Round Silos

Trevor Ellis — Thu, 12 Feb 2026 10:50:39 +0000

PETKUS Round Silos are practical for all types of grain, oilseeds, feed and industrial pellets. They consist of corrugated galvanized sheet steel which undergoes the Sendzimir process Z600 to provide high corrosion protection. The modular design of the round silos allows heights from 1 to 25 m and diameters from 3 to 32 m. The specifications of PETKUS steel round silos are calculated according to the product loads of ANSI/ASAE or EURO CODE. The construction is carried out in accordance to EUROCODE construction standards.

The roof of the silo is a self-supporting structure made of trapezoidal segments and equipped with ladders, filler caps and skylight observation. Round silos are equipped with inspection doors and wind rings and can also be equipped with roof and floor ventilation systems, a thermostat and a fill level sensor, resting platforms, railings and walkways.

PETKUS round silos are offered as flat bottom, hopper and loading silos. Flat bottom silos are used for long term storage, and are emptied with the help of a sweep auger according to the “first in, first out” principle. Hopper silos are emptied at a hopper inclination of 45° or 60°, depending on the properties of the product. Loading for trucks or railcars can with accomplished with a drive under loading cell.

Characteristics

Silo elements and struts constructed of sendzimir-galvanized steel
Cylinder heights up to 25 m
Hopper silo diameters up to 32 m
Substructure, supports and ascents depending on requirements
Outdoor installation

Technical Data:

		Flatbed Silo	Funnel Silo	Loading Silo
Diameter	(m)	ca. 4.6 – 32	ca. 3.5 – 12.0	ca. 3.0 – 6.0
Volume	(m³)	ca. 25000	ca. 2700

Profile Wall Silo

Trevor Ellis — Thu, 12 Feb 2026 10:50:38 +0000

PETKUS Profile Wall Silos are a modular system designed for limited space and are ideal for the storage of grain, corn, pellets and other granular and free flowing products. Profile wall silos are space-saving, stable and economical silo systems which offer compact customer-oriented solutions with regards to load and spatial requirements. The silo cells in a modular design can be installed as a battery of silos in a row or as a block with different heights and capacities. Silo cell blocks can be integrated into steel structures.

All silos meet the same structural requirements according to EUROCODE and consist of insulated wall elements bolted with countersunk flat head screws. Fast and high-quality on site assembly without welding is possible. The cell corners form hollow cavities which are filled with concrete after finishing the installation. Maximum possible volume without additional struts is 320 m ³. Sendzimir-galvanized steel or stainless steel sheets are used for the production of the individual elements for long-lasting corrosion protection. Every silo cell is equipped with a bolted outlet hopper.

Characteristics

Optional design with sendzimir-galvanized sheet steel or stainless steel
Profiled wall units with a length of 2000 mm up to 4000 mm in a 250 mm grid
Cell outlet hopper with a spot outlet
Substructure, frame, ladders and operating platforms
Complete solution including machine house (steel construction) possible
