Ventilation Louver "VT-250 Type"

Changing the filter is easy! The barrel treatment ensures smooth edges, providing peace of mind.

We would like to introduce our ventilated louver, the "VT-250 type." The standard specification uses knurled nuts for the filter fasteners. The IP45 specification allows for uniform coating thickness and, after baking, has a very high rust resistance due to a process called "cationic electrodeposition coating." Additionally, the IP55 salt damage prevention specification features a special three-layer mesh structure. We also offer the "VT-350 type" and "VT-500 type." 【Features】 <Standard Specification> ■ Mesh fastening nuts are knurled nuts ■ Made of stainless steel ■ Wide opening area ■ Smooth barrel treatment on the edges *For more details, please refer to the PDF document or feel free to contact us.

Principle of rain resistance

It shows the principle of rain protection of the IKP louver.

The principle of rain protection lies in colliding raindrops carried by wind blowing from left to right against the blades, transforming them into a water film due to the surface tension of the water, and causing them to fall. Only the rain directed towards the upper rain protection limit point in Figure 3 will collide with the inner blades. Rain coming from the front or below will be blocked by the outer blades. The rain that enters will fall through the central drainage outlet and be drained to the outside. This drainage outlet is slightly separated from the wall, so it does not dirty the wall even after years of use.

Principle of snow prevention

It shows the principle of snow protection for the IKP louver.

The principle of snow prevention involves installing snow-deflecting blades on the front of the IKP louver, raising the snow prevention wrap height, and preventing snow from blowing in from the front. The height of the large hood is diversified by the shape of the blades. Photo 4 shows the appearance of the IKP louver with snow-deflecting blades attached. Photo 5 depicts the situation during snowfall, where snow naturally falls off once it accumulates to a certain extent. Due to the angle of the photograph being from below, the front appears to be in a closed state because of the snow accumulation; however, in reality, it is in the situation shown in Figure 4, and the intake is hardly hindered. Additionally, in cases where a large amount of air is drawn in by fans or similar devices, the snow carried by the suction airflow collides with the IKP louver, causing the snow crystals to break apart and appear as diamond dust of less than 1 mm, which is then brought inside. As shown in Photo 5 and Figure 4, the intrusion of blown snow was effectively blocked. The snow carried in diamond dust form by the intake airflow came into contact with the rear filter and turned into water. By installing a water collection bucket between the rear filter of the IKP louver, the dead milk from the snow itself was effectively prevented.

"Outdoor unit louver" that is expected to solve problems and improve efficiency with the outdoor unit.

Eco-friendly product! We introduce the "Outdoor Unit Louver" that can be attached to your outdoor unit to change the direction of the exhaust.

The "Outdoor Unit Louver" is a louver that can be attached to your outdoor unit to change the direction of exhaust. The "Outdoor Unit Louver," which solves outdoor unit troubles by changing the direction of exhaust, is available for both general and commercial use. ◇ Change the direction of exhaust airflow If exhaust flows to neighboring properties or if it hits plants or walls due to close proximity, you can change the airflow direction. Depending on how it is installed, the airflow can be directed upward or sideways. ◇ Improve the operating efficiency of the outdoor unit In tight spaces, the heat emitted from the outdoor unit can cause the temperature of the air being drawn in to rise, leading to excessive power consumption as it tries to cool the indoor space, thus reducing the operating efficiency of the outdoor unit. Changing the airflow direction can lead to improved operating efficiency. 【Features】 ■ Improved operating efficiency of the outdoor unit ■ Control of airflow direction ■ ECO-friendly product *For more details, please refer to the PDF document or feel free to contact us.

Case study of perforated louver production [Tottori City Hall Main Building]

Louvered perforated panels that excel in design and functionality, enhancing the facade.

I was involved in the production of the perforated folded plate louvers installed in a gentle arc on the facade of the Tottori City Hall main building, including proposals for the design of the holes. The common areas feature perforated folded plates, while the office spaces and meeting rooms use louvered plates without holes, allowing for adjustments in direct sunlight control and privacy levels according to their intended use. Additionally, in terms of design, the perforated folded plates are painted to evoke the colors of the sand dunes of Tottori, and feature a hole pattern with three different hole diameters arranged randomly, along with four types of bending processes, creating varying expressions depending on the viewing angle.

Principle of IKP Louvers

An opening rate of over 90%, with rainproof, snowproof, and soundproof features! There are also achievements with an opening rate of 110% to 120%!

The "IKP Louver" originated from the intrusion of rainwater blown up by the sea breeze through the intake louver of an emergency generator soundproof shelter installed at the coastline. It was designed to effectively prevent wind and rain without utilizing a large hood or significantly altering the exterior, while maintaining an opening ratio of over 90% and ensuring low air resistance. The key idea lies in the diversification of a large single-shaped hood. The evolution of the actual concept is illustrated in photos 1, 2, and 3. 【Basic Structure for Expanding Opening Ratio】 Figure 1 illustrates the key point of the concept. It effectively prevents rain from below against the inner vertical opening surface, while keeping the outer opening horizontal to allow for an expanded free volume.

[Construction Example] Exterior

While inheriting a classical atmosphere, it possesses design and functionality that rival the main building.

We would like to introduce a case study of exterior construction handled by Okju. The Nihonbashi Mitsukoshi Main Store, New Building, consists of a total of 12 floors, including 2 basement levels and 10 above ground. It inherits the classical atmosphere of the main building while boasting a design and functionality that rival it. In particular, the decorative unit panels installed on the exterior of the top floor, which were constructed by our company, serve as a significant visual accent. Due to the volume and construction period, we repeatedly examined the construction methods, and combined vertical aluminum louvers and horizontal aluminum spandrels into large panels during the manufacturing process. These were then suspended using a large crane, and installation was carried out from the inside, which helped shorten the construction period and reduce external scaffolding. [Overview] ■ Name: Nihonbashi Mitsukoshi Main Store, New Building ■ Location: Tokyo ■ Design: Shimizu Corporation ■ Construction: Shimizu Corporation JV ■ Construction Area: Exterior aluminum louvers and rooftop crown aluminum panels <unit construction> *For more details, please refer to the PDF document or feel free to contact us.

[Construction Example] Station

We will vividly realize the image of the region through a variety of construction techniques.

We would like to introduce the construction case of a station handled by Okju. In the railway industry, pigeon damage to station buildings and platform roofs is a very serious problem. This time, West Japan Railway Company requested a finish using ceiling base materials, and as a result of development considerations, we adopted the "MB Louver," which can prevent pigeons from entering the ceiling interior. It is an extremely simple single-slope line louver composed of two types of components: the louver body using ceiling battens and the stringer. By selecting from several types of louver pitches, various expressions can be created, and if a specific pitch is chosen, it is also effective for pigeon prevention, allowing for a sharp ceiling design in places such as station buildings, platforms, and corridors, where movement lines should be considered. [Overview] ■ Name: JR Himeji Station / JR Okayama Station ■ Design: JR West Japan Consultants ■ Construction: Oitec Co., Ltd. / Obayashi Corporation JV ■ Construction Area: Platform Ceiling MB Louver *For more details, please refer to the PDF document or feel free to contact us.
