With the Oland standard range of rectangular ducts and fittings, strong, rigid and airtight duct systems can be built quickly and economically.Both ducts and fittings are manufactured to order.
Ducts and fittings are manufactured in accordance with DS447 (ventilation standards), and are designed for a pressure or Vacuum of up to 1000Pa. ( 100mm vc).
The Oeland duct system is manufactured to tightness class B, but can be ordered and manufactured to tight-ness class C.

The width of the sheets in the table is applicable to a pressure of 1000 Pa under the assumption that duct sides are dia-gonally crossed or are made in such way that the largest side length is over 300mm..
Bearings:
The distance between supports depends on the ducts’ tight-ness and the total cross sections. Supports distance should be highest 2m. Finally expansion bolts can be subjected to permanent load of 200N and short term with 1000N pr. bolt.

For flexible branching of rectangular ducts. Has a standard length of 100mm and is fitted with OS- strip in one end and a folded seam HF-40 on the other end
The ST has a standard length of 100mm and is fitted with an OS strip in one end and a folded seam HF40 on the larger end. For length bigger than 100mm use type SS.
The ducts are delivered in standard lenghts of 1000, 1500 and 2000. They can be produ-ced for special orders. Ducts are as standard fitted with OS.Check generally for alternative assembling codes. Ducts are braced when one side is exceeds 800mm.

It doesn’t matter from which side you look at the reduction piece. It is therefore important to define reference points. Reference point 1 is to your bottom left side(see fig. A)
Measure how reference point 2 is located in relation to reference point1. This will give offset c,d and
length L.See fig B if you are in doubt
whether it is + or -.

The JAL damper can be fitted to the duct by means of an OS20 flange. The fitting is done with C strip or mounting screws. The main body of the damper is made from un-treated aluminium.
The seals at the damper blades are made of a special rubber composition.The moving parts of the damper unit are outside the airstream.

Tightness classes at different pressure loss, measure after DIN 1964, EN 1751.
The airflow qv showsJAL curve in a diagram and also in a louvre damper tightness class. The pres-sure loss line is decided at the intersection as given and the airflow can therefore be decided to.
qvlba = 68,4 m3. h-1. m-2
Find the ducts average area from the following: S = A x B = 1,4 x 1,6 = 2,24 m2

Sound absorbers are manufactured with OS- connections to rectangular ducts. The duct is un-insulated or insu-lated internally. Various lining alternatives can be chosen depending of the operating conditions.
Sound absorbers can be of several configurations:LD: Straight sound absorbers of the absorption type.LD/LDH: Angled sound absorbers of the absorption type.LBB: Straight sound absorbers for limited building space.
Description:The sound absorbers comprises a duct made from warm galvanized steel plate and a number of built-in baffles. The duct is made as type KA.To facilitate cleaning, the sound absorbers are fitted with an inspection hatch with snap locks for easy handling.
Rectangular Sound absorber
Use the Windsound-programme for calculations. It can be downloaded for free from www.totalventilation.com
The LD is a duct with installed baffle(type LDB)The baffles are galvanised frames with black bars. To avoid damage the insulation is lined with black fragments.Maximum speed 15m/s.BT: baffle thicknessBA: baffle distance.
The sound level for the airflow velocity sound intensity should lie at least 7-10 db below the sound from the whole unit in the area where the sound absorber is placed.

The LD and the LH/LV types are sound absorbers of con-ventional type with baffles made from glass wool plates.
The LLD sound absorber is a type with high damping in the 250 Hz. octave band, and this is normal dimensio-ned. Moreover the damping of frequencies at 63, 125 and 500 Hz should be given priority over higher frequen-cies.
The LBB type is made especially for installations with limited space. This will give high damping in the lower octave bands and the damping element is placed at the largest side within the absorber.

ApplicationThe Oeland pressure monitors TK-1, TK-2, TK-3 and TK-4 is an automatic monitor series designed for control-ling over-/underpressure in ventilation systems and in industrial process air plants.If the pressure settings in the plant (in Pa) is not cor-rect, the monitor will give both a visual and an acoustic alarm signal. A pressure sensor panel is positioned in the control room next to the operator, and it is connected to a pressure transducer Climair 930.4 variants are available covering a range of 20- 2500 Pa.
