DERAMAX Rodent repeller plastic CLASIC 9V

Deramax-Klasik ultrasonic repeller

The Deramax-Klasik repellant is used to protect indoor and outdoor areas from martens, rodents and shrews. The device is completely safe and noiseless for humans. The pests are permanently disturbed by the ultrasonic signals of the scarecrow and leave the protected area in a short time. The operation of the device is ecological without the use of chemicals.

Pulse operation of the battery scarer:
One of the essential advantages of the Deramax-Klasik battery scarer is the optimized pulse operation, which allows generating ultrasonic signals with a very high sound pressure level with minimal energy consumption. The optimized pulse operation of the scarer and thus the pulsed energy consumption from the battery means a several times higher efficiency of using the battery capacity compared to common types of battery scarers. And that means a several-fold increase in battery life.

Resonance amplification of the ultrasound signal:
The Deramax-Klasik extinguisher uses resonant signal amplification, which is important for achieving the highest possible performance with the lowest possible energy consumption. We calibrate the frequencies generated by the electronic circuits of the scarecrow with the resonance frequencies of the used piezo transducers (ultrasound "emitters") within each production series.

Deramax-Klasik spreader power supply:
The Deramax-Klasik is a battery-powered scarecrow using a standard 9 V battery. The 9 V lithium battery will keep the device running for 12 months. A 9V alkaline battery will keep the scarecrow running for 6 months.

Target group of pests:
Martens, mice, rats, rats, shrews, weasels.

Scarecrow Resistance:
Indoor and outdoor use. The extinguisher is resistant to water, snow, humidity, dust, high temperature and frost (- 25°C to + 80°C).

Deramax-Klasik scarifier safety:
From the point of view of the effect on people, the Deramax-Klasik scarecrow does not disturb its surroundings with unpleasant noise, it is completely silent and safe. It meets the legal limits set for the maximum level of ultrasound. Our internal rules then go beyond applicable laws and take into account current medical scientific works and WHO recommendations for airborne ultrasound signals. At the same time, this scarecrow for martens and rodents has no negative effect on common domestic or farm animals, such as dogs, cats, horses, poultry, exotic birds, etc.

Comfort of operation:
The device does not need to be set up in any way, it works completely automatically. Just insert the battery and turn on the built-in switch.

Scarecrow Location:
A common solution for placing a scarecrow, and usually also the most practical solution, especially in the case of indoor use, is to place it on the ground in one of the corners of the protected area with the front facing towards the center of the protected area. However, it is also possible to fix the scarecrow using screws or double-sided adhesive tape to a fence, wall, post, window, door, etc., which is most suitable for use in outdoor areas. Even in this case, we recommend directing the front part of the spreader to the center of the protected area.

The range of effectiveness of the Deramax-Klasik scarecrow:
The highest effective distance in front of the scarecrow is up to 26 meters. The range of the effective area is up to 300 m². The effective angle of engagement is 120 degrees. The scarer therefore not only has high performance, but the special design of the device ensures the achievement of a very wide effective angle of engagement of 120 degrees, while even at the limit of the declared angle of engagement (that is, outside the main direction of signal emission), the scarer still generates at least 82% of the declared sound pressure level. Of course, the ultrasonic signal also spreads beyond the mentioned angle of engagement of 120 degrees, but the efficiency is already lower here, and therefore, for the sake of objectivity, we indicate an effective angle of engagement of "only" 120 degrees.

Number of scarecrows in one space:
Any number of ultrasonic scarers can be placed in one place and their signals are not negatively affected in any way. On the contrary, more repellers are usually used to protect especially larger or more fragmented areas, because a greater number of repellers (repellents) installed in one place means a significantly higher penetration of the protected space by the ultrasonic signal and the overall efficiency increases.

Official measurements:
