Two Types of Ventilation
There are two types of range hoods: external exhaust (طرد خارجي) and internal filtration (فلطار داخلي). The speaker recommends choosing both if possible, but if the duct is long, an external blower is needed to assist air extraction.
[00:30]
Ventilation and Duct Size
Ventilation via the hood's blower is crucial. The static pressure of the air from the external blower should be as high as possible. The minimum duct size is 4 inches, and 6 inches is good. Larger sizes are possible but may affect the ceiling (gypsum) installation.
[00:54]
Duct End and Maintenance
The duct must end with a wide opening to avoid blockage. It should be resistant to bacteria and easy to clean, filtering out grease and vapors, then recirculating air back into the kitchen.
[01:11]
Dual-Mode Hoods
Some hoods support both internal and external exhaust modes. The speaker recommends getting a hood that can do both, so you can switch based on your needs.
[01:24]
Suction Power and Kitchen Size
Suction power is measured in cubic meters per hour. The required capacity depends on kitchen size, whether it's open or closed, and the distance to the external outlet. If the duct is long, an external blower is necessary.
[01:36]
Design and Materials
Hoods come in various shapes: pyramid, ladder, island (for above a kitchen island), and corner. Materials include glass, steel, and different colors. The choice of design and material is purely aesthetic and does not affect performance.
[02:07]
Design vs. Performance
The difference between pyramid and ladder hoods is purely decorative, affecting the finish and the look of the surrounding cabinets. It has no impact on suction power or filtration method.
When choosing a range hood, prioritize ventilation type and duct size for performance, but remember that design and materials are purely aesthetic. A dual-mode hood with a high-pressure blower is the most flexible option.

[00:00] هناك نوعين طرد خارجي وفلطار داخلي هذا ما أنصح به لو يمكنك إختيار الاثنين ولو المخرج عيد أكثر من قدرة الشفوات يجب أن أركب بلور خارجي يساعد جفت الهواء البار
[00:30] وفيه تهوية عن طريق شفاط المنضخ او ودي مهمة جدا. يعني قطر
[00:42] الضغط النائل للهواء من شفاط بره كل ما كان اكبر كل ما يكون افضل. ما يقلش عن اربعة بوصة ده المينيموم. وما يزيدش عن ستة بوصة ده كويس. عايز تعمل اكتر من كده ما فيش مشكلة. بس هيأثر
[00:54] على سقوط الجبس. ولازم يتعامل في الاخر بنهاية واسعة عشان ما اصارش على او ما يكتمش. طبعا لازم يكون مقاوم البكتيريا وسهل
[01:11] يفلتره ويشيل منه الدهون والابخيرة. ويتلقى في المطبخ تاني. وفي شفاطات بتشتغل طرد داخلي وطرد خارجي. احنا حبيت تشغل وطرد خارجي بيشتغل. حبيت تشغله في الاتر بيشتغل. ده اللي بنصح بيه لو في يدك تجيب الاتنين. ربما اول حاجة من ناحية
[01:24] الشفط فيه نوعين. طرد خارجي وفلتر اخر. لها دعوة او هو الشفاط ده بيخرج ويفلتر كم متر مكعب كل ساعة. وطبعا دي فيها برامج كتير زي حجم ومساحة المطبخ معفولة لمفتوح ولو المخرج بعيد
[01:36] اكتر من قدرة الشفاط لازم اركب بلور خارجي يساعد شفط الهواء البار. تاني حاجة بالنسبة للمدخنة الشكل والديكور. في شفاط هرمي وفي شفات سلم وفي شفات ايلند اللي هو بتحط فوق الجزيرة وفي شفات كورنر بتحط في كورنر واشكالهم مختلفة والماتيريال اللي
[01:51] بتعملوا منها برضو مختلفة في زجاجة وفي ستيل وفي الوان مختلفة واختلاف الالوان ده بيكون حسب التصميم والشكل فقط. ملوش دعوة بقدرة الشفات او طريقة الترد. الفرق بين الشفات الهرمي والسلم بيختلف الفينش كديكور وشكل الوحيات حواليه.
[02:07] ملوش زين.
